[Ibn Sina--psychology and psychological disorders].

Ebu Ali Husein Ibn Ali Ibn Sina (or Avicenna) was primarily a philosopher with amusing knowledge, who dealt in all aspects of art of medicine, astronomer, poet, musician and psychologist. This giant with an encyclopedic knowledge has dealt in almost all scientific branches or praxis with the great success. Numerous statements of his have been cornerstone of many sciences for centuries; and some of them are (in the era of computers and Internet) still current. The best known treatise on medicine of his is El-Kanun, consisting of five volumes, wherein all medical achievements (including psychology, psychiatry and neurology) of that period were described clearly. In his psychology, Ibn Sina (Avicenna) analyses the essence of human soul, mind, psychical streams, intellectum, dreams and prophecy, man's desires etc. in details. It is unnecessary to point out how much these items are actual in the contemporary psychology. Ibn al-Nefis has described systematically the symptoms and recovery of "head sick" (including headaches, cerebral sick like cranitis, letargy, coma, demency, melancholy, insomnia, nightmares, epilepsy, appoplexy, paralysis, spasm and many others) in his Mujez al-Kanun, that is synopsis of Ibn Sina Kanun. We need much time to see magnificance of this philosopher, that is best known as the great one among the physicians. His writings could be found in whole Bosnia, but there were many few that would study him and his works. It is out task to enable the future generations not only to know those works exist, but, also, to realize the essence of this marvelous genius; because there are very few people that can be compared to him.
