In applied mathematics, he made fundamental contributions to mechanics, hydraulics, acoustics, optics, and astronomy. He was based in the Imperial Academy of Sciences in St.
Petersburg at the Imperial Academy — Broadly speaking, Enlightenment science greatly valued empiricism and rational thought and was embedded with the Enlightenment ideal of advancement and progress.
The study of science, under the heading of natural philosophy , was divided into physics and a conglomerate grouping of chemistry and natural history , which included anatomy , biology, geology, mineralogy and zoology.
Societies and academies were also the backbone of the maturation of the scientific profession. Another important development was the popularization of science among an increasingly literate population. Some historians have marked the 18th century as a drab period in the history of science.
Scientific academies and societies grew out of the Scientific Revolution as the creators of scientific knowledge in contrast to the scholasticism of the university. Official scientific societies were chartered by the state to provide technical expertise. In reference to this growth, Bernard de Fontenelle coined the term "the Age of Academies" to describe the 18th century.
The influence of science also began appearing more commonly in poetry and literature during the Enlightenment. Some poetry became infused with scientific metaphor and imagery, while other poems were written directly about scientific topics. After Newton's death in , poems were composed in his honour for decades. Hume and other Scottish Enlightenment thinkers developed a " science of man ",  which was expressed historically in works by authors including James Burnett , Adam Ferguson , John Millar and William Robertson , all of whom merged a scientific study of how humans behaved in ancient and primitive cultures with a strong awareness of the determining forces of modernity.
Modern sociology largely originated from this movement  and Hume's philosophical concepts that directly influenced James Madison and thus the U. Constitution and as popularised by Dugald Stewart , would be the basis of classical liberalism. In , Adam Smith published The Wealth of Nations , often considered the first work on modern economics as it had an immediate impact on British economic policy that continues into the 21st century.
Smith acknowledged indebtedness and possibly was the original English translator. Cesare Beccaria , a jurist, criminologist, philosopher and politician and one of the great Enlightenment writers, became famous for his masterpiece Of Crimes and Punishments , later translated into 22 languages,  which condemned torture and the death penalty and was a founding work in the field of penology and the Classical School of criminology by promoting criminal justice.
Another prominent intellectual was Francesco Mario Pagano , who wrote important studies such as Saggi Politici Political Essays, , one of the major works of the Enlightenment in Naples; and Considerazioni sul processo criminale Considerations on the criminal trial, , which established him as an international authority on criminal law. The Enlightenment has long been hailed as the foundation of modern Western political and intellectual culture.
This thesis has been widely accepted by Anglophone scholars and has been reinforced by the large-scale studies by Robert Darnton , Roy Porter and most recently by Jonathan Israel. John Locke , one of the most influential Enlightenment thinkers,  based his governance philosophy in social contract theory , a subject that permeated Enlightenment political thought. The English philosopher Thomas Hobbes ushered in this new debate with his work Leviathan in Hobbes also developed some of the fundamentals of European liberal thought : the right of the individual; the natural equality of all men; the artificial character of the political order which led to the later distinction between civil society and the state ; the view that all legitimate political power must be "representative" and based on the consent of the people; and a liberal interpretation of law which leaves people free to do whatever the law does not explicitly forbid.
While quite different works, Locke, Hobbes and Rousseau agreed that a social contract, in which the government's authority lies in the consent of the governed,  is necessary for man to live in civil society. Locke defines the state of nature as a condition in which humans are rational and follow natural law, in which all men are born equal and with the right to life, liberty and property.
However, when one citizen breaks the Law of Nature both the transgressor and the victim enter into a state of war, from which it is virtually impossible to break free. Therefore, Locke said that individuals enter into civil society to protect their natural rights via an "unbiased judge" or common authority, such as courts, to appeal to. Contrastingly, Rousseau's conception relies on the supposition that "civil man" is corrupted, while "natural man" has no want he cannot fulfill himself.
Natural man is only taken out of the state of nature when the inequality associated with private property is established. This is embodied in the sovereignty of the general will , the moral and collective legislative body constituted by citizens. Locke is known for his statement that individuals have a right to "Life, Liberty and Property" and his belief that the natural right to property is derived from labor. Tutored by Locke, Anthony Ashley-Cooper, 3rd Earl of Shaftesbury wrote in "There is a mighty Light which spreads its self over the world especially in those two free Nations of England and Holland; on whom the Affairs of Europe now turn".
The philosophes argued that the establishment of a contractual basis of rights would lead to the market mechanism and capitalism , the scientific method , religious tolerance and the organization of states into self-governing republics through democratic means.
In this view, the tendency of the philosophes in particular to apply rationality to every problem is considered the essential change. Although much of Enlightenment political thought was dominated by social contract theorists, both David Hume and Adam Ferguson criticized this camp. Hume's essay Of the Original Contract argues that governments derived from consent are rarely seen and civil government is grounded in a ruler's habitual authority and force.
It is precisely because of the ruler's authority over-and-against the subject, that the subject tacitly consents and Hume says that the subjects would "never imagine that their consent made him sovereign", rather the authority did so. In his An Essay on the History of Civil Society , Ferguson uses the four stages of progress, a theory that was very popular in Scotland at the time, to explain how humans advance from a hunting and gathering society to a commercial and civil society without "signing" a social contract.
Both Rousseau's and Locke's social contract theories rest on the presupposition of natural rights , which are not a result of law or custom, but are things that all men have in pre-political societies and are therefore universal and inalienable.
The most famous natural right formulation comes from John Locke in his Second Treatise , when he introduces the state of nature. For Locke, the law of nature is grounded on mutual security or the idea that one cannot infringe on another's natural rights, as every man is equal and has the same inalienable rights.
These natural rights include perfect equality and freedom, as well as the right to preserve life and property. Locke also argued against slavery on the basis that enslaving oneself goes against the law of nature because one cannot surrender one's own rights: one's freedom is absolute and no-one can take it away.
Additionally, Locke argues that one person cannot enslave another because it is morally reprehensible, although he introduces a caveat by saying that enslavement of a lawful captive in time of war would not go against one's natural rights.
As a spill-over of the Enlightenment, nonsecular beliefs expressed first by Quakers and then by Protestant evangelicals in Britain and the United States emerged. To these groups, slavery became "repugnant to our religion" and a "crime in the sight of God. The leaders of the Enlightenment were not especially democratic, as they more often look to absolute monarchs as the key to imposing reforms designed by the intellectuals.
Voltaire despised democracy and said the absolute monarch must be enlightened and must act as dictated by reason and justice — in other words, be a "philosopher-king". In several nations, rulers welcomed leaders of the Enlightenment at court and asked them to help design laws and programs to reform the system, typically to build stronger states. These rulers are called "enlightened despots" by historians. Joseph was over-enthusiastic, announcing many reforms that had little support so that revolts broke out and his regime became a comedy of errors and nearly all his programs were reversed.
In Poland, the model constitution of expressed Enlightenment ideals, but was in effect for only one year before the nation was partitioned among its neighbors. More enduring were the cultural achievements, which created a nationalist spirit in Poland. Frederick the Great , the king of Prussia from to , saw himself as a leader of the Enlightenment and patronized philosophers and scientists at his court in Berlin.
Voltaire, who had been imprisoned and maltreated by the French government, was eager to accept Frederick's invitation to live at his palace.
Frederick explained: "My principal occupation is to combat ignorance and prejudice The Enlightenment has been frequently linked to the French Revolution of One view of the political changes that occurred during the Enlightenment is that the " consent of the governed " philosophy as delineated by Locke in Two Treatises of Government represented a paradigm shift from the old governance paradigm under feudalism known as the " divine right of kings ". In this view, the revolutions of the late s and early s were caused by the fact that this governance paradigm shift often could not be resolved peacefully and therefore violent revolution was the result.
Clearly a governance philosophy where the king was never wrong was in direct conflict with one whereby citizens by natural law had to consent to the acts and rulings of their government. Alexis de Tocqueville proposed the French Revolution as the inevitable result of the radical opposition created in the 18th century between the monarchy and the men of letters of the Enlightenment.
These men of letters constituted a sort of "substitute aristocracy that was both all-powerful and without real power". This illusory power came from the rise of "public opinion", born when absolutist centralization removed the nobility and the bourgeoisie from the political sphere.
The "literary politics" that resulted promoted a discourse of equality and was hence in fundamental opposition to the monarchical regime. Enlightenment era religious commentary was a response to the preceding century of religious conflict in Europe, especially the Thirty Years' War.
For moderate Christians, this meant a return to simple Scripture. John Locke abandoned the corpus of theological commentary in favor of an "unprejudiced examination" of the Word of God alone. He determined the essence of Christianity to be a belief in Christ the redeemer and recommended avoiding more detailed debate.
Enlightenment scholars sought to curtail the political power of organized religion and thereby prevent another age of intolerant religious war. A number of novel ideas about religion developed with the Enlightenment, including deism and talk of atheism. According to Thomas Paine , deism is the simple belief in God the Creator , with no reference to the Bible or any other miraculous source.
Instead, the deist relies solely on personal reason to guide his creed,  which was eminently agreeable to many thinkers of the time. Wilson and Reill note: "In fact, very few enlightened intellectuals, even when they were vocal critics of Christianity, were true atheists. Rather, they were critics of orthodox belief, wedded rather to skepticism, deism, vitalism, or perhaps pantheism".
That is, since atheists gave themselves to no Supreme Authority and no law and had no fear of eternal consequences, they were far more likely to disrupt society. He would be a god to himself, and the satisfaction of his own will the sole measure and end of all his actions. The "Radical Enlightenment"   promoted the concept of separating church and state,  an idea that is often credited to English philosopher John Locke — For Locke, this created a natural right in the liberty of conscience, which he said must therefore remain protected from any government authority.
These views on religious tolerance and the importance of individual conscience, along with the social contract, became particularly influential in the American colonies and the drafting of the United States Constitution. He previously had supported successful efforts to disestablish the Church of England in Virginia  and authored the Virginia Statute for Religious Freedom. The Enlightenment took hold in most European countries, often with a specific local emphasis.
For example, in France it became associated with anti-government and anti-Church radicalism, while in Germany it reached deep into the middle classes, where it expressed a spiritualistic and nationalistic tone without threatening governments or established churches.
In France, the government was hostile, and the philosophes fought against its censorship, sometimes being imprisoned or hounded into exile. The British government, for the most part, ignored the Enlightenment's leaders in England and Scotland, although it did give Isaac Newton a knighthood and a very lucrative government office.
A common theme among most countries which derived Enlightenment ideas from Europe was the intentional non-inclusion of Enlightenment philosophies pertaining to slavery. Originally during the French Revolution, a revolution deeply inspired by Enlightenment philosophy, "France's revolutionary government had denounced slavery, but the property-holding 'revolutionaries' then remembered their bank accounts.
For instance, during the Haitian Revolution England and the United States supported France "rather than giving aid to Saint-Domingue's anti-colonial struggle. The very existence of an English Enlightenment has been hotly debated by scholars. The majority of textbooks on British history make little or no mention of an English Enlightenment. However, its leading intellectuals such as Edward Gibbon ,  Edmund Burke and Samuel Johnson were all quite conservative and supportive of the standing order.
Porter says the reason was that Enlightenment had come early to England and had succeeded so that the culture had accepted political liberalism, philosophical empiricism, and religious toleration of the sort that intellectuals on the continent had to fight for against powerful odds. Furthermore, England rejected the collectivism of the continent and emphasized the improvement of individuals as the main goal of enlightenment.
In the Scottish Enlightenment, Scotland's major cities created an intellectual infrastructure of mutually supporting institutions such as universities, reading societies, libraries, periodicals, museums and masonic lodges. Several Americans, especially Benjamin Franklin and Thomas Jefferson , played a major role in bringing Enlightenment ideas to the New World and in influencing British and French thinkers. Thinkers such as Paine, Locke and Rousseau all take Native American cultural practices as examples of natural freedom.
During the Enlightenment there was a great emphasis upon liberty , republicanism and religious tolerance. There was no respect for monarchy or inherited political power. Deists reconciled science and religion by rejecting prophecies, miracles and Biblical theology. Prussia took the lead among the German states in sponsoring the political reforms that Enlightenment thinkers urged absolute rulers to adopt. There were important movements as well in the smaller states of Bavaria, Saxony, Hanover and the Palatinate.
In each case, Enlightenment values became accepted and led to significant political and administrative reforms that laid the groundwork for the creation of modern states. The reforms were aided by the country's strong urban structure and influential commercial groups and modernized pre Saxony along the lines of classic Enlightenment principles.
Before , the German upper classes looked to France for intellectual, cultural and architectural leadership, as French was the language of high society. Christian Wolff — was the pioneer as a writer who expounded the Enlightenment to German readers and legitimized German as a philosophic language.
Johann Gottfried von Herder — broke new ground in philosophy and poetry, as a leader of the Sturm und Drang movement of proto-Romanticism. Weimar Classicism Weimarer Klassik was a cultural and literary movement based in Weimar that sought to establish a new humanism by synthesizing Romantic, classical and Enlightenment ideas.
The movement from until involved Herder as well as polymath Johann Wolfgang von Goethe — and Friedrich Schiller — , a poet and historian. Herder argued that every folk had its own particular identity, which was expressed in its language and culture.
This legitimized the promotion of German language and culture and helped shape the development of German nationalism. Schiller's plays expressed the restless spirit of his generation, depicting the hero's struggle against social pressures and the force of destiny. German music, sponsored by the upper classes, came of age under composers Johann Sebastian Bach — , Joseph Haydn — and Wolfgang Amadeus Mozart — Kant's work contained basic tensions that would continue to shape German thought — and indeed all of European philosophy — well into the 20th century.
The German Enlightenment won the support of princes, aristocrats and the middle classes and it permanently reshaped the culture. In , Prussia issued an "Edict on Religion" that forbade preaching any sermon that undermined popular belief in the Holy Trinity and the Bible.
The goal was to avoid skepticism, deism and theological disputes that might impinge on domestic tranquility. Men who doubted the value of Enlightenment favoured the measure, but so too did many supporters. German universities had created a closed elite that could debate controversial issues among themselves, but spreading them to the public was seen as too risky.
This intellectual elite was favoured by the state, but that might be reversed if the process of the Enlightenment proved politically or socially destabilizing. The Enlightenment played a distinctive, if small, role in the history of Italy.
Leopold II of Tuscany abolished the death penalty in Tuscany and reduced censorship. From Naples, Antonio Genovesi — influenced a generation of southern Italian intellectuals and university students.
His textbook "Diceosina, o Sia della Filosofia del Giusto e dell'Onesto" was a controversial attempt to mediate between the history of moral philosophy on the one hand and the specific problems encountered by 18th-century commercial society on the other.
It contained the greater part of Genovesi's political, philosophical and economic thought — guidebook for Neapolitan economic and social development. Pietro Verri was a leading economist in Lombardy. In fact, the upheaval of the Age Enlightenment would ripple around the world, and not just in political arenas. Science, culture and the arts were influenced heavily by the ideals and values of the Age of Enlightenment, and other nation's wars for independence from colonial rulers, such as those in South America, were soon to follow.

I agree with Nicole and Lauren that, while we are becoming more enlightened over time, we are still not fully enlightened, and probably will not be for a long time. If we were fully enlightened, we would not need numerous news shows and radio stations that tend to display their biased political beliefs on both ends of the spectrum. From the ultra-conservative FOX to the uber-liberal NBC, it is sometimes apparent that their agendas are secretly to attempt to sway people to their republican and democratic sides, respectively.
If we were really as enlightened as we would like to be, we would not need so much reassurance about our daily and life-long choices. I believe we are becoming more and more dependent rather than independent. We constantly rely on technology and others to take care of things for us and we are becoming complacent. We are forgetting that hard work will pay off in the end. We really need to retake control of our own lives and make our own decisions.
As Americans, we are obliged to be aware of what is going on in our own world. I just hope we can become an informed population once again and not be manipulated by media with definite agendas. I believe that yes, we are in an age of enlightenment, not an enlightened age, because people are simply too complacent and lazy to seek their own truths.
Like others have said above, the media, our families and friends, and technology all sway our opinions and keep an individual from searching for their own truths and living only by what they believe. If we can lall ive our own lives without being so easily swayed by the opinions and beliefs of others, then we will truly have an enlightened age.
I agree that we are in an age of enlightenment rather than an enlightened age, but I think there are many aspects other than political media contributing to this state. Editar playlist.

The Enlightenment has long been hailed as the foundation of modern western political and intellectual culture.
It brought political modernization to the west, in terms of focusing on democratic values and institutions, and the creation of modern, liberal democracies. The English philosopher Thomas Hobbes ushered in a new debate on government with his work Leviathan in John Locke and Rousseau also developed social contract theories. Enlightenment era religious commentary was a response to the preceding century of religious conflict in Europe. Enlightenment thinkers sought to curtail the political power of organized religion, and thereby prevent another age of intolerant religious war.
A number of novel ideas developed, including Deism belief in God the Creator, with no reference to the Bible or any other source and atheism. The latter was much discussed but there were few proponents. Many, like Voltaire, held that without belief in a God who punishes evil, the moral order of society was undermined.
The radical Enlightenment promoted the concept of separating church and state, an idea often credited to Locke. For Locke, this created a natural right in the liberty of conscience, which he said must therefore remain protected from any government authority.
These views on religious tolerance and the importance of individual conscience, along with the social contract, became particularly influential in the American colonies and the drafting of the United States Constitution. Rationalism, or a belief that we come to knowledge through the use of logic, and thus independently of sensory experience, was critical to the debates of the Enlightenment period, when most philosophers lauded the power of reason but insisted that knowledge comes from experience.
Rationalism—as an appeal to human reason as a way of obtaining knowledge—has a philosophical history dating from antiquity. While rationalism, as the view that reason is the main source of knowledge, did not dominate the Enlightenment, it laid critical basis for the debates that developed over the course of the 18th century.
Descartes was the first of the modern rationalists. He thought that only knowledge of eternal truths including the truths of mathematics and the foundations of the sciences could be attained by reason alone, while the knowledge of physics required experience of the world, aided by the scientific method. Leibniz, Spinoza, and Descartes were all well-versed in mathematics, as well as philosophy, and Descartes and Leibniz contributed greatly to science as well.
Since the Enlightenment, rationalism is usually associated with the introduction of mathematical methods into philosophy, as seen in the works of Descartes, Leibniz, and Spinoza. Although rationalism and empiricism are traditionally seen as opposing each other, the distinction between rationalists and empiricists was drawn at a later period, and would not have been recognized by philosophers involved in Enlightenment debates.
Furthermore, the distinction between the two philosophies is not as clear-cut as is sometimes suggested. For example, Descartes and John Locke, one of the most important Enlightenment thinkers, have similar views about the nature of human ideas.
Proponents of some varieties of rationalism argue that, starting with foundational basic principles, like the axioms of geometry, one could deductively derive the rest of all possible knowledge. The philosophers who held this view most clearly were Baruch Spinoza and Gottfried Leibniz, whose attempts to grapple with the epistemological and metaphysical problems raised by Descartes led to a development of the fundamental approach of rationalism.
