History of Science: Antiquity through the Renaissance

Comprehensive vocabulary flashcards covering the development of Western natural philosophy, ancient medicine, classical cosmologies, and Renaissance anatomical traditions.

Ontology

The branch of philosophy concerned with the study of being, existence, and the basic structure of reality, including matter and form.

Epistemology

The philosophical study of knowledge, examining its nature, origin, scope, methods, and limits.

Cosmology

The study of order, pattern, and structure in the natural world, encompassing the origin, large-scale structure, evolution, and fate of the universe.

Historical sensitivity

The historiographical principle that ancient science must be judged by the goals, methods, and cultural assumptions of its own time rather than modern standards.

MUL.APIN

An ancient Babylonian astronomical text and constellation compendium recording star groups meaningful to Babylonian celestial traditions.

Homeric worldview

An early Greek outlook in which occurrences in nature are treated as particular, unique events driven by personal divine emotions, vendettas, and direct interventions.

Milesian worldview

A naturalistic approach that leaves the gods out of explanations, grouping natural events into broad generalizations and seeking unified physical causes through monism and critical assessment.

Apeiron

The 'boundless' or unlimited substance proposed by the Milesian philosopher Anaximander as the fundamental origin of all things.

Incubation

The ancient medical ritual of sleeping on the grounds of a healing sanctuary, such as a temple of Asclepius, in order to receive a healing dream epiphany from the god.

Votive tablet

An inscribed tablet left at a religious healing temple as an offering of prayer or thanksgiving to deities like Asclepius and Hygieia.

The Sacred Disease

A Hippocratic treatise attacking popular superstitions surrounding epilepsy, asserting that the condition arises from natural humoral imbalances (excess phlegm) rather than divine possession.

Humors

The four bodily fluids—blood, phlegm, yellow bile, and black bile—whose proper balance was believed in Hippocratic medicine to maintain health.

Actors' categories

The concepts, terms, and classifications used by historical figures who experienced events and practices in real time within their own culture.

Analysts' categories

Modern conceptual frameworks and retrospective diagnostic terms applied backward by contemporary historians to interpret past events.

Logos

The rational, ordering principle identified by Heraclitus that governs perpetual change and dynamic cosmic balance.

Stadium Paradox

A paradox formulated by Zeno of Elea demonstrating that motion is impossible because an object must cross an infinite number of midpoints to reach any destination.

Reductio ad absurdum

A method of argument that refutes an opponent's proposition by demonstrating that following its premises leads to a logical contradiction or absurdity.

Dialectic

The art of logical inquiry and debate through conversational questioning, reasoning, and testing arguments against common opinion.

Four roots

The elemental substances identified by Empedocles—fire (Zeus), air (Hera), earth (Aidoneus), and water (Nestis)—which combine and separate under the cosmic forces of Love and Strife.

Nous

The cosmic Mind proposed by Anaxagoras as the external, rational ordering principle that initiates the mixing and separation of all substances.

Atomism

The metaphysical doctrine founded by Leucippus and Democritus asserting that reality consists entirely of uncuttable, subsensible particles moving randomly in an infinite void.

Bastard knowledge

Democritus's term for sensory perception (sight, hearing, smell, taste, and touch), which provides obscure judgments as opposed to legitimate rational insight.

Realm of Forms

Plato's intelligible realm of eternal, changeless perfections, of which physical objects in the sensible corporeal world are merely imperfect replicas.

Demiurge

The divine craftsman and mathematician in Plato's Timaeus who brings order out of disorder by fashioning the cosmos according to geometric principles and proportions.

Platonic solids

The five regular polyhedra used in Plato's cosmology to represent the submicroscopic geometric particles of the elements: tetrahedron (fire), octahedron (air), icosahedron (water), cube (earth), and dodecahedron (the universe).

Four causes

Aristotle's explanatory system for understanding natural change: material cause (underlying matter), formal cause (essence or structure), efficient cause (primary mover or agent), and final cause (purpose or goal).

Teleology

The philosophical view that natural processes, structures, and changes are directed toward inherent ends, functions, or goals (telos).

Aether

The indestructible fifth element in Aristotelian cosmology that makes up the celestial spheres and is characterized by eternal, uniform circular motion.

Two-sphere model

The classical astronomical framework composed of a stationary, spherical Earth positioned in the center, surrounded by a vast, rotating spherical heavens carrying the stars.

Ecliptic

The apparent annual circular path of the sun against the background of fixed stars through the zodiac, inclined at $23\frac{1}{2}^\circ$ to the celestial equator.

Circumpolar stars

Stars situated close enough to the celestial pole that their daily circular paths never dip below the observer's local horizon.

Retrograde motion

The periodic, apparent westward backward motion of planets against the fixed stars, presenting an anomaly to simple geocentric circular orbits.

Eccentric

A planetary model in which the center of a planet's uniform circular orbit is displaced away from the position of the Earth to account for variations in apparent speed.

Epicycle-on-deferent

A geometric model where a planet travels in a small uniform circle (epicycle), whose center in turn revolves along a larger circular path (deferent) around the center of the cosmos.
