Understanding the world. Cultivating judgement.
Works, testimonies and further readings are distinguished. Dates refer to composition or first publication, as specified in each entry.
This catalogue covers the surviving treatises of the Aristotelian corpus, giving separate pages to its major units and explicitly listing the contents of the grouped Short Natural Treatises. Pseudepigraphic and disputed works are marked. The verified inventory contains Rose’s 680 numbered units (1886), including the five fragments of the Appendix dubiorum; his epistolary section, numbers 651–670, also appears separately. These units may combine several quotations or testimonies and represent neither 680 works nor a completely surviving correspondence. Rose, Ross and Gigon use non-interchangeable numbering systems. Later discoveries, letter traditions excluded by Rose and his unnumbered Life of Aristotle remain outside this inventory.
Explore letters and fragmentsThis short treatise distinguishes ways of saying what something is: substance, quantity, quality, relation and the remaining categories. Ordinary examples introduce a difficult question: is the inquiry about words, their meanings or the things themselves?
Explore this workVisit the source(new tab)Aristotle investigates statements capable of truth or falsity: names, verbs, affirmation, negation and opposed propositions. The celebrated sea-battle example asks how present truth relates to contingent future events.
Explore this workVisit the source(new tab)The two books investigate deductions whose conclusions follow necessarily from given premises. Aristotle organizes syllogistic figures, conversions of propositions and modal arguments, separating formal validity from the truth of premises.
Explore this workVisit the source(new tab)What distinguishes scientific understanding from simply knowing that something occurs? Aristotle examines demonstration, first principles, definitions and causes. Scientific explanation must show why its object could not be otherwise in the relevant respect.
Explore this workVisit the source(new tab)Eight books organize discussion from accepted opinions, or endoxa. Dialectic does not directly demonstrate scientific principles: it examines theses, follows their consequences and prepares critical work on definitions.
Explore this workVisit the source(new tab)The treatise analyzes arguments that seem to refute an opponent without actually doing so. Verbal ambiguity, confused questions and changes of meaning produce an anatomy of argumentative error.
Explore this workVisit the source(new tab)Eight books seek the principles of natural beings, characterized by an internal source of motion and rest. Matter, form, change, infinity, place, void and time are investigated before the question of a first mover.
Explore this workVisit the source(new tab)Four books present a finite, ordered and eternal universe, then examine celestial motions and the elements. Earth occupies the center while celestial bodies follow supposedly natural circular motion.
Explore this workVisit the source(new tab)The treatise distinguishes substantial coming-to-be from ordinary alteration. Contact, mixture and elemental transformation explain how one thing arises from another without emerging absolutely from nothing.
Explore this workVisit the source(new tab)Four books investigate atmospheric phenomena, waters, earthquakes, minerals and material transformations. The scope greatly exceeds modern weather studies, connecting terrestrial events to a general theory of elements and exhalations.
Explore this workVisit the source(new tab)Three books investigate the principle of life, from nutrition to thinking. Soul is not initially a ghost residing inside a body: it is the form of an organized natural body capable of living.
Explore this workVisit the source(new tab)This collection studies perception, memory, sleep and the conditions of life. It comprises On Sense and Sensible Objects; On Memory and Recollection; On Sleep and Waking; On Dreams; On Divination in Sleep; On Length and Shortness of Life; On Youth and Old Age, Life and Death; and On Respiration.
Explore this workThis extensive investigation collects anatomical differences, reproductive patterns, behavior and habitats. It organizes facts requiring explanation rather than providing either a collection of fables or a modern species taxonomy.
Explore this workVisit the source(new tab)Four books explain why animals possess particular parts and how those parts contribute to their lives. The first book develops a method; the others examine tissues, organs and bodily differences.
Explore this workVisit the source(new tab)Five books investigate reproduction, embryonic development, heredity and variable traits. Aristotle asks how living organization develops progressively, connecting bodily materials with a formative principle.
Explore this workThe treatise seeks principles shared by animal locomotion, from bodily support to the role of desire. It connects joints, the representation of a goal and the initiation of action.
Explore this workVisit the source(new tab)This study compares the mechanisms by which animals walk, swim and fly. Limb number, flexion and bodily arrangement become problems in functional anatomy.
Explore this workVisit the source(new tab)Fourteen books collect investigations of first causes, being as being, substance and actuality. They preserve several routes of inquiry, unresolved difficulties and vocabularies that cannot be reduced to one formula.
Explore this workVisit the source(new tab)Ten books investigate human flourishing through virtue, choice, justice, friendship, pleasure and contemplation. Happiness means activity across a complete life, also dependent on material circumstances and relationships.
Explore this workVisit the source(new tab)This other ethical investigation studies happiness, virtue, voluntary action, friendship and the relation between human life and the divine. Its argument follows a distinctive course despite shared Nicomachean themes.

Explore this workEight books investigate community, citizenship, constitutions, civil conflict, education and the best regime. Aristotle compares institutions and asks how their arrangement makes particular forms of collective life possible.
Explore this workVisit the source(new tab)Three books analyze means of persuasion, audience emotions, character, style and speech arrangement. Rhetoric becomes the ability to discern what may persuade in a particular situation.
Explore this workVisit the source(new tab)The surviving text chiefly analyzes tragedy and epic, their representational means and the organization of plot. It asks how an artwork produces an intelligible experience through composed actions.

Explore this workAristotle’s dialogues and public writings survive chiefly through quotations and testimonies. Attested titles include On Philosophy, Eudemus or On the Soul, Protrepticus, Gryllus or On Rhetoric, On Poets, On Justice, On the Good and On Ideas.
Explore this workDiogenes Laertius preserves a will, a hymn to Virtue and an epigram for Hermias. His catalogue mentions letters to Philip, Alexander, Antipater, Mentor, Ariston, Olympias, Hephaestion, Themistagoras and Philoxenus, alongside other collections; it does not reproduce a complete correspondence.
