Lucretius in the context of "Aeneid"

Ancient Roman philosophy is philosophy as it was practiced in the Roman Republic and its successor state, the Roman Empire. Roman philosophy includes philosophy written in Latin as well as philosophy written in Greek in the late Republic and Roman Empire. Important early Latin-language writers include Lucretius, Cicero, and Seneca the Younger. Greek was a popular language for writing about philosophy, so much so that the Roman Emperor Marcus Aurelius chose to write his Meditations in Greek.

Criticism of religion involves criticism of the validity, concept, or ideas of religion. Historical records of criticism of religion go back to at least 5th century BCE in ancient Greece, in Athens specifically, with Diagoras "the Atheist" of Melos. In ancient Rome, an early known example is Lucretius' De rerum natura from the 1st century BCE.

Every exclusive religion on Earth (as well as every exclusive world view) that promotes exclusive truth-claims necessarily denigrates the truth-claims of other religions. Thus, some criticisms of religion become criticisms of one or more aspects of a specific religious tradition. Critics of religion in general may view religion as one or more of: outdated, harmful to the individual, harmful to society, an impediment to the progress of science or humanity, a source of immoral acts or customs, and a political tool for social control.

The Anxiety of Influence: A Theory of Poetry is a 1973 book by Harold Bloom on the anxiety of influence in writing poetry. It was the first in a series of books that advanced a new "revisionary" or antithetical approach to literary criticism. Bloom's central thesis is that poets are hindered in their creative process by the ambiguous relationship they necessarily maintain with precursor poets. While admitting the influence of extraliterary experience on every poet, he argues that "the poet in a poet" is inspired to write by reading another poet's poetry and will tend to produce work that is in danger of being derivative of existing poetry, and, therefore, weak. Because poets historically emphasize an original poetic vision in order to guarantee their survival into posterity, the influence of precursor poets inspires a sense of anxiety in living poets. Thus Bloom attempts to work out the process by which the small minority of 'strong' poets manage to create original work in spite of the pressure of influence. Such an agon (a vain attempt by a writer to resolve the conflict between his ideas and those of a much more influential predecessor), Bloom argues, depends on six revisionary ratios, which reflect Freudian and quasi-Freudian defense mechanisms, as well as the tropes of classical rhetoric.

Before writing this book, Bloom spent a decade studying the Romantic poets of the early nineteenth century. This is reflected in the emphasis given to those poets and their struggle with the influence of John Milton, Robert Burns, and Edmund Spenser. Other poets analyzed range from Lucretius and Dante to Walt Whitman, Wallace Stevens, and John Ashbery. In The Anxiety of Influence and other early books, Bloom claimed that influence was particularly important for post-enlightenment poets. Conversely, he suggested that influence might have been less of a problem for such poets as Shakespeare and Ben Jonson. Bloom later changed his mind, and the most recent editions of The Anxiety of Influence include a preface claiming that Shakespeare was troubled early in his career by the influence of Christopher Marlowe. The book itself is divided into six major categories, called "six revisionary ratios" by Bloom. They are clinamen, tessera, kenosis, daemonization, askesis, and apophrades.

De rerum natura (Latin: [deː ˈreːrʊn naːˈtuːraː]; On the Nature of Things) is a first-century BC didactic poem by the Roman poet and philosopher Lucretius (c. 99 BC – c. 55 BC) with the goal of explaining Epicurean philosophy to a Roman audience. The poem, written in some 7,400 dactylic hexameters, is divided into six untitled books, and explores Epicurean physics through poetic language and metaphors. Namely, Lucretius explores the principles of atomism; the nature of the mind and soul; explanations of sensation and thought; the development of the world and its phenomena; and explains a variety of celestial and terrestrial phenomena. The universe described in the poem operates according to these physical principles, guided by fortuna ("chance"), and not the divine intervention of the traditional Roman deities.

Gaius Memmius (c. 99 – c. 49 BC, incorrectly called Gemellus, "The Twin") was a Roman politician, orator and poet. He is most famous as the dedicatee of Lucretius' De Rerum Natura, and for his appearances in the poetry of Catullus.

Gian Francesco Poggio Bracciolini (Italian: [dʒaɱ franˈtʃesko ˈpɔddʒo brattʃoˈliːni]; 11 February 1380 – 30 October 1459), usually referred to simply as Poggio Bracciolini, was an Italian scholar and an early Renaissance humanist. He is noted for rediscovering and recovering many classical Latin manuscripts, mostly decaying and forgotten in German, Swiss, and French monastic libraries. His most celebrated finds are De rerum natura, the only surviving work by Lucretius, De architectura by Vitruvius, lost orations by Cicero such as Pro Sexto Roscio, Quintilian's Institutio Oratoria, Statius' Silvae, Ammianus Marcellinus' Res Gestae (Rerum gestarum Libri XXXI), and Silius Italicus's Punica, as well as works by several minor authors such as Frontinus' De aquaeductu, Nonius Marcellus, Probus, Flavius Caper, and Eutyches.

Clinamen (/klaɪˈneɪmən/; plural clinamina, derived from clinare, to incline) is the unpredictable swerve of atoms in the atomistic doctrine of Epicurus. This swerving, according to Lucretius, provides the "free will which living things throughout the world have". Lucretius never gives the primary cause of the deflections.

According to Lucretius, the unpredictable swerve occurs "at no fixed place or time":
