P.F. Strawson 
Individuals [PDF ebook] 

Since its publication in 1959, Individuals has become a modern philosophical classic. Bold in scope and ambition, it continues to influence debates in metaphysics, philosophy of logic and language, and epistemology. Peter Strawson’s most famous work, it sets out to describe nothing less than the basic subject matter of our thought. It contains Strawson’s now famous argument for descriptive metaphysics and his repudiation of revisionary metaphysics, in which reality is something beyond the world of appearances.Throughout, Individuals advances some highly influential and controversial ideas, such as ‘non-solipsistic consciousness’ and the concept of a person a ‘primitive concept’
