Xenophon would object to being left out.
There actually is little evidence that Aristotle had any great impact on Alexander. He was a tutor of Alexander for only two years beginning when Alexander was 13. Alexander made no reference to Aristotle after he became an adult, and the extensive conquests of his former pupil elicited not a line of comment from Aristotle. The life of contemplation sometimes intersects with the life of action, but not in this instance.

It would seem that Alexander’s interest in philosophy, if he ever had any, vanished in favor of military adventures. It would also seem that he had little interest in improving the system of government beyond simply the control of territory and people. That he died early was probably more of a benefice than his contemporaries realized at the time.
The Persian Empire was in decline compared to the Greek City States as demonstrated by the March to the Sea of the 10000. Alexander performed the historical function of bringing to an end the Persian Empire and spreading Hellenism throughout the Near East. Alexander had some interesting ideas of melding the Persian and the Greek. His death led to the rule of the Diadochi and paved the way ultimately for Rome and the spreading of Christianity throughout the Empire. What Alexander accomplished in his short life had long echoes.
