This is the translation of the following Aristotelian treatises: On Sense and Sensibles, On Memory and Reminiscence, On Sleep and Waking, On Dreams, On Divination in Sleep, On Longevity and Brevity of Life, On Youth and Old Age, as well as Life and Death, and Breathing.

The comments mainly contain explanations of difficult translational and interpretative points, which, where deemed necessary, are based on the relevant approaches of the main commentators of the work.

In addition to the ancient text, the translation, and the comments, the book includes an introduction, a summary of the argumentation of each chapter, essential bibliography, a glossary, and an index of names and ancient passages.
