Aristotle was a Greek philosopher and polymath during the Classical period in Ancient Greece. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics and government.

"The Nicomachean Ethics" addresses the question of how the individual should best live.

"Metaphysics" examines what can be asserted about any being insofar as it is and not because of any special qualities that it may possess.

"Poetics" is the earliest surviving work of dramatic theory and the first extant philosophical treatise on literary theory.

In "Rhetoric", the philosopher identifies rhetoric as one of the three key elements of philosophy, along with logic and dialectic.

"On Sense and the Sensible" is one of the short treatises that make up the Parva Naturalia. "On Memory and Reminiscence" deals with sensory perception.

"On Dreams" examines questions like whether dreams pertain to the faculty of thought or to that of sense-perception, whilst "On Prophesying by Dreams" is a discussion on precognitive dreams.

"On Youth and Old Age" is a comparison of the temperament of youth with that of old age, and considers middle age the best of all conditions.

"On Longevity and Shortness of Life" examines whether there is one cause that makes everything long-lived, or whether the cause is diverse for plants and animals, whilst "On Life and Death" considers living beings as food burners: They nourish themselves, and in some cases they have the capacity for higher functions such as mental perception.
