Description

This book explores Wittgenstein s unsettling remark in the Tractatus that the only necessity that exists is logical necessity. It suggests that the notion of necessity is a primitive notion, and, as such, both a requirement for human cognition and constitutive of rational thought.

On this basis, the book then reexamines some of the perennial questions of philosophy including logic itself, beauty, law, truth and the concept of God. All of these topics are seen to be closely related to the notion of necessity. It is argued that if logical necessity is the only necessity that exists, then Kant s notion of the subjective necessity of aesthetic judgments must be reconsidered. Likewise, metaphysical, moral, and practical necessity must all be revised.

Finally, a new dimension is added to the analysis. It is shown that the notion of logical necessity is human in its origin, and yet also absolute. This insight reopens the possibility of logical absolutism
