The conception of man in modern philosophy is often traced in the subjectivistic models back to Descartes. Those who examine these conceptions later consider them as the full process to empty man of the metaphysical essence ascribed to him in ancient philosophies. So the modern conception of man as the subject takes shape and develops as an entity without soul, whose nature is interpreted according to the laws of modern psychological and natural sciences. This scientific conception implies that, in the modern period, the finite man needs no longer to be considered as a metaphysical being. In this work, Mahmoud Khatami will instead suggest an otherwise interesting notion of man by stepping back toward Persian Illuminative thought within which he follows his project of ontetic philosophy and rethinks aspects of the ontetic nature of man in a metaphysical sense, which is generated from a spiritual source and transcends towards a spiritual and moral life. This book should be especially useful to professionals in philosophy and those who are interested in philosophical anthropology.
