A Compendium.

Avi Sion,  Ph. D.

First published, 2013.


Logical Philosophy: A Compendium brings together five works by Avi Sion published in the years 2002-06, namely: Phenomenology (2003), Volition and Allied Causal Concepts (2004), Meditations (2006), Ruminations (2005), and Buddhist Illogic (2002).

These works together define what may be termed ‘Logical Philosophy’, i.e. philosophical discourse distinguished by its steadfast reliance on inductive and deductive logic to resolve epistemological and ontological issues.

Note that the works are placed in a logical rather than chronological order. This collection does not include work done on The Logic of Causation in the same period (published in 2003, 2005).
