Ethical Problems was traditionally counted as the fourth book of the Quaestiones. The work is a discussion of ethical issues based on Aristotle, and contains responses to questions and problems deriving from Alexander's school. It is likely that the work was not written by Alexander himself, but rather by his pupils on the basis of debates involving Alexander.

On the Principles of the Universe is preserved in Arabic translation. This treatise is not mentioned in surviving Greek sources, but it enjoyed great popularity in the Muslim world, and a large number of copies have survived. The main purpose of this work is to give a general account of Aristotelian cosmology and metaphysics, but it also has a polemical tone, and it may be directed at rival views within the Peripatetic school. Alexander was concerned with filling the gaps of the Aristotelian system and smoothing out its inconsistencies, while also presenting a unified picture of the world, both physical and ethical. The topics dealt with are the nature of the heavenly motions and the relationship between the unchangeable celestial realm and the sublunar world

Instead, providence is a power that emanates from the heavens to the sublunar region, and is responsible for the generation and destruction of earthly things, without any direct involvement in the lives of individuals.
