Cosmological Argument - History

History

Plato (c. 427–347 BC) and Aristotle (c. 384–322 BC) both posited first cause arguments, though each had certain notable caveats. Plato posited a basic argument in The Laws (Book X), in which he argued that motion in the world and the Cosmos was "imparted motion" that required some kind of "self-originated motion" to set it in motion and to maintain that motion. Plato posited a "demiurge" of supreme wisdom and intelligence as the creator of the Cosmos in his work Timaeus.

Aristotle argued against the idea of a first cause, often confused with the idea of a "prime mover" or "unmoved mover" (πρῶτον κινοῦν ἀκίνητον or primus motor) in his Physics and Metaphysics. Aristotle's famous argument was contrary to the atomist's depiction of a non-eternal cosmos which, he argued, would require an efficient first cause, a notion that Aristotle took to demonstrate a critical flaw in their reasoning. However, a non-eternal cosmos, with both a beginning and an end, would later come to reflect the prevalent theological beliefs in medieval Europe. By simply denying that an efficient first cause is problematic, being easily explained as the creative action of an omnipotent God, medieval theologians re-purposed and enhanced Aristotle's argument, as if the intention had been to prove God's existence. Like Plato, Aristotle believed in an eternal cosmos with no beginning and no end (which in turn follows Parmenides' famous statement that "nothing comes from nothing"). In what he called "first philosophy" or metaphysics, Aristotle did intend a theological correspondence between the prime mover and deity (presumably Zeus); functionally, however, he provided an explanation for the apparent motion of the "fixed stars" (now understood as the daily rotation of the Earth). According to his theses, immaterial unmoved movers are eternal unchangeable beings that constantly think about thinking, but being immaterial, they're incapable of interacting with the cosmos and have no knowledge of what transpires therein. From an "aspiration or desire", the celestial spheres, imitate that purely intellectual activity as best they can, by uniform circular motion. The unmoved movers inspiring the planetary spheres are no different in kind from the prime mover, they merely suffer a dependency of relation to the prime mover. Correspondingly, the motions of the planets are subordinate to the motion inspired by the prime mover in the sphere of fixed stars. Aristotle's natural theology admitted no creation or capriciousness from the immortal pantheon, but maintained a defense against dangerous charges of impiety.

Plotinus, a third-century Platonist, taught that the One transcendent absolute caused the universe to exist simply as a consequence of its existence - "creatio ex deo." His disciple Proclus stated 'The One is God'.

Centuries later, the Islamic philosopher Avicenna (c. 980–1037) inquired into the question of being, in which he distinguished between essence (Mahiat) and existence (Wujud). He argued that the fact of existence could not be inferred from or accounted for by the essence of existing things, and that form and matter by themselves could not originate and interact with the movement of the Universe or the progressive actualization of existing things. Thus, he reasoned that existence must be due to an agent cause that necessitates, imparts, gives, or adds existence to an essence. To do so, the cause must coexist with its effect and be an existing thing.

Steven Duncan, writes that "it was first formulated by a Greek-speaking Syriac Christian neo-Platonist, John Philoponus." Who claims to find a contradiction between the Greek pagan insistence on the eternity of the world and the Aristotelian rejection of the existence of any actual infinite." Referring to the argument as the "'Kalam' cosmological argument", Duncan asserts that it "received its fullest articulation at the hands of Muslim and Jewish exponents of Kalam ("the use of reason by believers to justify the basic metaphysical presuppositions of the faith)."

Thomas Aquinas (c. 1225–1274), a theologian in Medieval Europe, adapted the argument he found in his reading of Aristotle and Avicenna to form one of the most influential versions of the cosmological argument. His conception of First Cause was the idea that the Universe must have been caused by something that was itself uncaused, which he asserted was God.

Many other philosophers have posited cosmological arguments both before and since Aquinas. The versions sampled in the following sections are representative of the most common derivations of the argument.
