Christian humanism in the context of "Nontheism"

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.

In Eastern Orthodox (Palamite) theology, there is a distinction between the essence (ousia) and the energies (energeia) of God. It was formulated by Gregory Palamas (1296–1359) as part of his defense of the Athonite monastic practice of Hesychasm against the charge of heresy brought by the humanist scholar and theologian Barlaam of Calabria.

Eastern Orthodox theologians generally regard this distinction as a real distinction, and not just a conceptual distinction. Historically, Western Christian thought, since the time of the Great Schism, has tended to reject the essence–energies distinction as real in the case of God, characterizing the view as a heretical introduction of an unacceptable division in the Trinity and suggestive of polytheism.

Herman Boerhaave (Dutch: [ˈɦɛrmɑm ˈbuːrˌɦaːvə], 31 December 1668 – 23 September 1738) was a Dutch chemist, botanist, Christian humanist, and physician. He is sometimes regarded as the founder of clinical teaching and of the modern academic hospital along with Venetian physician Santorio Santorio (1561–1636). Boerhaave introduced the quantitative approach into medicine, along with his pupil Albrecht von Haller (1708–1777). He was the first to isolate the chemical urea from urine. He was the first physician to put thermometer measurements to clinical practice. His motto was Simplex veri sigillum: 'Simplicity is the sign of the truth'. He is often hailed as the "Dutch Hippocrates".

Marsilio Ficino (Italian: [marˈsiːljo fiˈtʃiːno]; Latin name: Marsilius Ficinus; 19 October 1433 – 1 October 1499) was an Italian scholar and Catholic priest who was one of the most influential humanist philosophers of the early Italian Renaissance. He was an astrologer, a reviver of Neoplatonism in touch with the major academics of his day, and the first translator of Plato's complete extant works into Latin. His Florentine Academy, an attempt to revive Plato's Academy, influenced the direction and tenor of the Italian Renaissance and the development of European philosophy.

François Rabelais (UK: /ˈræbəleɪ/ RAB-ə-lay, US: /ˌræbəˈleɪ/ -⁠LAY; French: [fʁɑ̃swa ʁablɛ]; born between 1483 and 1494; died 1553) was a French writer who has been called the first great French prose author. A humanist of the French Renaissance and Greek scholar, he attracted opposition from both Protestant theologian John Calvin and from the hierarchy of the Catholic Church. Though in his day he was best known as a physician, scholar, diplomat, and Catholic priest, later he became better known as a satirist for his depictions of the grotesque, and for his larger-than-life characters.

Living in the religious and political turmoil of the Reformation, Rabelais treated the great questions of his time in his novels. Rabelais admired Erasmus and like him is considered a Christian humanist. He was critical of medieval scholasticism and lampooned the abuses of powerful princes and popes.

Justus Lipsius (Joest Lips or Joost Lips; October 18, 1547 – March 23, 1606) was a Flemish Catholic philologist, philosopher, and humanist. Lipsius wrote a series of works designed to revive ancient Stoicism in a form that would be compatible with Christianity. The most famous of these is De Constantia (On Constancy). His form of Stoicism influenced a number of contemporary thinkers, creating the intellectual movement of Neostoicism. He taught at the universities in Jena, Leiden, and Leuven.
