Abstract

In this book Timothy O’Connor combines an investigation of modal epistemology with a fresh look at the traditional contingency version of the cosmological argument.

This provides the context in which he asks the existence question, ‘Why do the particular contingent objects there are exist and undergo the events they do?’. Wisely avoiding the Principle of Sufficient Reason he argues that the existence question is answered by, and only by, positing a necessary being that is a se in the sense of not depending on any other being.Another important feature of O’Connor's treatment is that he does not accept the difficult scholastic doctrine of divine simplicity, instead relying on the weaker thesis that the essential divine attributes are mutually entailing. Yet again he resists the thesis of the immutability of God, allowing that a necessary being can have accidental attributes and hence can change by acquiring knowledge of the free acts and/or random events that occur. In addition he combines the cosmological argument with the argument from fine-tuning so that the latter is used to support the thesis that the …
