This philosopher invented a term for a category of names that group abstract general ideas according to their natural similitude; those are called "sortals".
One of this philosopher's works was dated a decade earlier than previously thought in a landmark 1960 edition by Peter Laslett. This philosopher invented a term for a category of names that group abstract general ideas according to their natural similitude; those are called "sortals". He argued that there must exist an indefinable, quality-less base to which qualities called "accidents" must adhere. That notion of "pure (*) substance in general" was postulated by this secretary to Anthony Ashley Cooper, Earl of Shaftesbury. The first part of a work by him attacks the Patriarcha of Robert Filmer. In that work, he proposed that whatever a man has "mixed his labor with" is his property. For 10 points, name this philosopher of An Essay Concerning Human Understanding and Two Treatises of Government.
