This chapter on creation and eternity in medieval philosophy focuses on arguments for the world's age drawn from the nature of time. To this end, there are four main sections. The first covers proofs for the eternity of the world taken from the nature of time, with an emphasis on Aristotle's original argument for that thesis and then Avicenna's modal version of the proof. The second deals with rejoinders, based upon non‐Aristotelian conceptions of time, to proofs for the eternity of (...) the world with a focus on Augustine's idealist conception of time. The third section takes up positive arguments for the temporal finitude of the cosmos and the difficulties surrounding the idea of infinite past time. The final section canvasses the “agnostic position” of Ibn Tufayl, Moses Maimonides, and Thomas Aquinas concerning the question of the cosmos's age. (shrink)

Recently, the Intelligent Design (ID) movement has challenged the claim of many in the scientific establishment that nature gives no empirical signs of having been deliberately designed. In particular, ID arguments in biology dispute the notion that neo-Darwinian evolution is the only viable scientific explanation of the origin of biological novelty, arguing that there are telltale signs of the activity of intelligence which can be recognized and studied empirically. In recent years, a number of Catholic philosophers, theologians, and scientists have (...) expressed opposition to ID. Some of these critics claim that there is a conflict between the philosophy of St. Thomas Aquinas and that of the ID movement, and even an affinity between Aquinas’s ideas and theistic Darwinism. We consider six such criticisms and find each wanting. (shrink)
