Logical positivism
If we want to classify his philosophy from the point of view of the degree of abstractness and its relation to real life, then we would say that Dr. Zaki Naguib lines up with those philosophers who expressed their philosophy through literature and art rather than through building metaphysical constructs. For, he did not build a metaphysical construct, despite his use of 'Logical positivism' in its abstract form. In this sense he is closer to Sartre, Nietzsche and Kierkegaard, in modern ages, and to Abu Hayan Altawhidi in ancient Arabic philosophy than to Russell, Kant and Ibn Rusd. Hence he was rightly referred to as 'the philosopher of literature writers and the writer of the philosophers'.
