Then submitted to the Bukhara man named Abu Abdullah Alnatli and was called the philosophical, got a guest in the house of Ibn Sina Flmh a bit of philosophy during his stay with them. He began Alnatli book in logic. However, Ibn Sina had imagined logical issues better than him, and often dazzling teacher, his knowledge of logic and its specificity minutes. He took Ibn Sina then read the books of logic and commentaries by himself even mastered the science and stop the Dakkaigah. And then proceeded to study the book of the assets of Engineering and also read to his teacher, but he did not read it only five or six forms of the first book, then took over after learning that the rest of the book himself. As he left his mentor to Bukhara, taken Ibn Sina in the study of natural science, and opened him the doors of science ascended medicine Vdersh and excelled at the short-term, they did not find Ibn Sina of the hard sciences it well until it became distinct in it, and resorted to by elders of Medicine read by the types and treatments which comes from experience, and has treated patients did not receive a wage for doing so. I unloaded Q yen for the lesson was lost to science, did not slept the whole night and the length of one day not worked in the non-science, and during this period did not cut off from the study of jurisprudence and all parts of philosophy. And has had his own way in the understanding of the issues and arguments, it was arranged that he wants to understand the matter in the form of a syllogism, and strive to find met East and exploration, because it was believed that he could not understand the issue only if it is known to reduce East.

We have completed the Ibn Sina from the collection of all the sciences of language and jurisprudence, accounting and engineering, logic and philosophy of medicine at the age of eighteen, and stood on its details and intricacies and objectives, but note one eluded him did not understand the science of the post of Nature (Theology). He read Aristotle's book in this science did not understand anything of it, and re-read it forty times even save it by heart without understanding.

Auctioneer told him that the book price only three dinars and its owner in need of money for it, Vachtrah hereof, if the book is Al-Farabi in the purposes of post-nature. Ibn Sina, he sped to the house opened up and read it as tongue-tied, in the case because he saves Kate August Aristotle, rejoiced at this and believe much on the poor. But science has not matured in his mind until he reached the perceptions of men, and gained experience of travel. Ibn Sina began his travels after the troubled state affairs Samani, and after he died and his father at the age of twenty-two years old at the time, went out from Bukhara to Kirkang, and was wearing a costume scholars, Vokrema Prince algorithm and decided to have a monthly salary of doing.
