AtheismAtheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists. The first individuals to identify themselves as atheists lived in the 18th century during the Age of Enlightenment.
PhysicsPhysics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. A scientist who specializes in the field of physics is called a physicist. Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest.
OntologyIn metaphysics, ontology is the philosophical study of being, as well as related concepts such as existence, becoming, and reality. Ontology addresses questions like how entities are grouped into and which of these entities exist on the most fundamental level. Ontologists often try to determine what the categories or highest kinds are and how they form a system of categories that encompasses the classification of all entities. Commonly proposed categories include substances, properties, relations, states of affairs, and events.
AtomismAtomism (from Greek ἄτομον, atomon, i.e. "uncuttable, indivisible") is a natural philosophy proposing that the physical universe is composed of fundamental indivisible components known as atoms. References to the concept of atomism and its atoms appeared in both ancient Greek and ancient Indian philosophical traditions. Leucippus is the earliest figure whose commitment to atomism is well attested and he is usually credited with inventing atomism. He and other ancient Greek atomists theorized that nature consists of two fundamental principles: atom and void.
Cynicism (philosophy)Cynicism (κυνισμός) is a school of thought in ancient Greek philosophy, originating in the Classical period and extending into the Hellenistic and Roman Imperial periods. According to Cynicism, people are reasoning animals and the purpose of life and the way to gain happiness is to achieve virtue, in agreement with nature, following one's natural sense of reason by living ascetically and shamelessly free from social constraints.
LucretiusTitus Lucretius Carus (ˈtaɪtəs_luːˈkriːʃəs , ˈtɪtʊz lʊˈkreːti.ʊs ˈkaːrʊs; 99 – 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, and which usually is translated into English as On the Nature of Things—and somewhat less often as On the Nature of the Universe. Lucretius has been credited with originating the concept of the three-age system that was formalised in 1836 by C. J. Thomsen.
UtilitarianismIn ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for all affected individuals. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility as: That property in any object, whereby it tends to produce benefit, advantage, pleasure, good, or happiness .
CyrenaicsThe Cyrenaics or Kyrenaics (Kyrēnaïkoí), were a sensual hedonist Greek school of philosophy founded in the 4th century BCE, supposedly by Aristippus of Cyrene, although many of the principles of the school are believed to have been formalized by his grandson of the same name, Aristippus the Younger. The school was so called after Cyrene, the birthplace of Aristippus. It was one of the earliest Socratic schools. The Cyrenaics taught that the only intrinsic good is pleasure, which meant not just the absence of pain (as it did for Epicurus), but positively enjoyable sensations.
De rerum naturaDe rerum natura (deː ˈreːrʊn naːˈtuːraː; On the Nature of Things) is a first-century BC didactic poem by the Roman poet and philosopher Lucretius (99 BC-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.
HoraceQuintus Horatius Flaccus (ˈkɥiːn̪t̪ʊs̠ (h)ɔˈraːt̪iʊs̠ ˈfɫ̪akːʊs̠; 8 December 65 BC – 27 November 8 BC), commonly known in the English-speaking world as Horace (ˈhɒrɪs), was the leading Roman lyric poet during the time of Augustus (also known as Octavian). The rhetorician Quintilian regarded his Odes as just about the only Latin lyrics worth reading: "He can be lofty sometimes, yet he is also full of charm and grace, versatile in his figures, and felicitously daring in his choice of words.
