Pierre Gassendi in the context of "Atomism"

The Age of Enlightenment (also the Age of Reason) was a period in the history of Europe and Western civilization during which the Enlightenment, an intellectual and cultural movement, flourished, emerging in the late 17th century in Western Europe and reaching its peak in the 18th century, as its ideas spread more widely across Europe and into the European colonies, in the Americas and Oceania. Characterized by an emphasis on reason, empirical evidence, and scientific method, the Enlightenment promoted ideals of individual liberty, religious tolerance, progress, and natural rights. Its thinkers advocated for constitutional government, the separation of church and state, and the application of rational principles to social and political reform.

The Enlightenment emerged from and built upon the Scientific Revolution of the 16th and 17th centuries, which had established new methods of empirical inquiry through the work of figures such as Galileo Galilei, Johannes Kepler, Francis Bacon, Pierre Gassendi, Christiaan Huygens and Isaac Newton. Philosophical foundations were laid by thinkers including René Descartes, Thomas Hobbes, Baruch Spinoza, and John Locke, whose ideas about reason, natural rights, and empirical knowledge became central to Enlightenment thought. The dating of the period of the beginning of the Enlightenment can be attributed to the publication of Descartes' Discourse on the Method in 1637, with his method of systematically disbelieving everything unless there was a well-founded reason for accepting it, and featuring his dictum, Cogito, ergo sum ('I think, therefore I am'). Others cite the publication of Newton's Principia Mathematica (1687) as the culmination of the Scientific Revolution and the beginning of the Enlightenment. European historians traditionally dated its beginning with the death of Louis XIV of France in 1715 and its end with the outbreak of the French Revolution in 1789. Many historians now date the end of the Enlightenment as the start of the 19th century, with the latest proposed year being the death of Immanuel Kant in 1804.

Titus Lucretius Carus (/ˈtaɪtəs luːˈkriːʃəs/ TY-təs loo-KREE-shəs; Latin: [ˈtitus luˈkreːti.us ˈkaːrus]; c. 99 – October 15, 55 BC) was a Roman poet and philosopher. His only known work is the philosophical poem De rerum natura, a didactic work about the tenets and philosophy of Epicureanism, which usually is translated into English as On the Nature of Things—and somewhat less often as On the Nature of the Universe. Very little is known about Lucretius's life; the only certainty is that he was either a friend or client of Gaius Memmius, to whom the poem was addressed and dedicated. De rerum natura was a considerable influence on the Augustan poets, particularly Virgil (in his Aeneid and Georgics, and to a lesser extent on the Eclogues) and Horace. The work was almost lost during the Middle Ages, but was rediscovered in 1417 in a monastery in Germany by Poggio Bracciolini. It played an important role both in the development of atomism (Lucretius was an important influence on Pierre Gassendi) and the efforts of various figures of the Enlightenment era to construct a new Christian humanism.

Gassendi is a large lunar impact crater feature located at the northern edge of Mare Humorum. The crater was named after French astronomer Pierre Gassendi by the IAU in 1935. The formation has been inundated by lava during the formation of the mare, so only the rim and the multiple central peaks remain above the surface. The outer rim is worn and eroded, although it retains a generally circular form. A smaller crater – Gassendi A – intrudes into the northern rim, and joins a rough uplift at the northwest part of the floor. The crater pair bear a curious resemblance to a diamond ring.

In the southern part of the crater floor is a semi-circular ridge-like formation that is concentric with the outer rim. It is in the southern part where the rim dips down to its lowest portion, and a gap appears at the most southern point. The rim varies in height from as little as 200 meters to as high as 2.5 kilometers above the surface. The floor has numerous hummocks and rough spots. There is also a system of fractures that criss-crosses the floor, named the Rimae Gassendi.

Corpuscularianism, also known as corpuscularism (from Latin corpusculum 'little body' and -ism), is a set of theories that explain natural transformations as a result of the interaction of particles (minima naturalia, partes exiles, partes parvae, particulae, and semina). It differs from atomism in that corpuscles are usually endowed with a property of their own and are further divisible, while atoms are neither. Although often associated with the emergence of early modern mechanical philosophy, and especially with the names of Thomas Hobbes, René Descartes, Pierre Gassendi, Robert Boyle, Isaac Newton, and John Locke, corpuscularian theories can be found throughout the history of Western philosophy.

Grand Siècle (French pronunciation: [ɡʁɑ̃ sjɛkl]) or Great Century refers to the period of French history during the 17th century, under the reigns of Louis XIII and Louis XIV.

The period was notable for its development of art, music and literature, along with the construction of the Palace of Versailles, the effects of the French Wars of Religion, and the impacts of the Thirty Years' War, which made France the dominant power in Europe instead of Spain. Significant figures during this period include gardener André Le Nôtre, architects François Mansart, Louis Le Vau and Jules Hardouin-Mansart, painters Nicolas Poussin, Simon Vouet, Claude Lorrain, Georges de La Tour, Philippe de Champaigne, Charles Le Brun, sculptors Pierre Puget, François Girardon and Antoine Coysevox, playwrights Pierre Corneille, Molière and Jean Racine, the poets François de Malherbe, Jean de La Fontaine and Nicolas Boileau, writers Madame de La Fayette, Charles Perrault, composers Henri Dumont, Jean-Baptiste Lully, Marc-Antoine Charpentier, Michel Richard Delalande, André Campra, Henri Desmarest, Marin Marais and François Couperin, philosophers René Descartes, Blaise Pascal, Antoine Arnauld, Nicolas Malebranche, Pierre Gassendi, La Rochefoucauld, La Bruyere, and Pierre Bayle.
