ABSTRACT
Philosophy tries to deal with questions about the nature and reality of things in the world such as God, time or causality. In the philosophical sense, the nature of something which is ‘natural’ is the character of something which is accessible to scientific study and the nature of something non-natural is an attempt to describe something which is abstract or beyond the reach of space and time. The ‘world’ is the universe that contains not only all apparently real or less tangible things but also all possible things, or things that we can only possibly imagine. Logic can be justified because it makes a certain way of coherent thinking possible, though checking it against some known prototype cannot prove it. Clarity and word meaning are crucially important in philosophy and an ability to define clearly the meanings of words is important.
