Omniscience is an attribute having to do with knowledge; it is the attribute of “having knowledge of everything.” Many philosophers consider omniscience to be an attribute possessed only by a divine being, such as the God of Western monotheism. However, the Eastern followers of Jainism allow omniscience to be an attribute of some human beings. But what exactly is it to be omniscient?
The term’s root Latin words are “omni” (all) and “scientia” (knowledge), and these suggest a rough layman’s definition of omniscience as “knowledge of everything.” Yet even though this definition may be somewhat useful, there are a number of questions which the definition alone does not address.
First, there is the general question of what exactly our human knowledge is and whether or not an understanding of human knowledge can be applied to God. For example, does God have beliefs? And what kind of evidence does God need for these beliefs to count as knowledge? There is also the question of what exactly this “everything” in the definition is supposed to mean. Does God know everything which is actual but not all that is possible? Does God know the future, and if so, how exactly? This last question is a perennial difficulty and will require a thorough investigation. (Continue article)
