Abstract

Mulla Sadra divides secondary intelligible concepts into philosophical and logical types. He says that secondary intelligble concepts are often referred to as rational predicates with abstract principles. Yet, sometimes these concepts are so defined that they include logical concepts which precede the intelligible ones.Defining logical secondary intelligible concepts as qualities which do not exist m reality, Mulla Sadra limits their existence to their manifestation in mental being. Recognizing philosophical secondary intelligible concepts on a par with the logical ones, Mulla Sadra states that concommitants of quiddities fall in the same philosophical category. He speaks of two possibilities regarding philosophical concepts; either they are all subjective considerations and have no existence whatsoever, or not.He considers logical secondary intelligible concepts as mental qualities of the superior intelligible concepts, and philosophical concepts as qualities of concrete beings.Mulla Sadra concludes that secondary intelligible concepts have real qualification and mental occurence.
