ΑΙΣΘΗΜΑ
In classical Greek philosophy, αἴσθημα primarily refers to sensory perception and the impression received through the senses. It is not merely an emotion in the modern sense, but the very foundation of knowledge derived from the sensible world. Its lexarithmos (269) suggests a connection to the idea of fundamental apprehension and the structure of experience.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, αἴσθημα (to) is initially defined as "perception, sensation, impression." It is a noun derived from the verb αἰσθάνομαι and denotes the result or object of sensory perception. In classical philosophy, particularly in Plato and Aristotle, αἴσθημα is central to epistemology and psychology, as it constitutes the raw material of knowledge acquired through the five senses.
In Plato, αἴσθημα is often contrasted with νοῦς (intellect) and ἐπιστήμη (knowledge), being considered a lower form of cognition, prone to error and change, unlike the immutable truth of the Forms. Nevertheless, it is recognized as a necessary first step towards apprehending reality. For instance, in the «Republic», sensory experience serves as the starting point for the ascent to the world of intelligible Forms.
Aristotle, in his work «On the Soul» (Περί Ψυχής), develops a more systematic theory of sensation (αἴσθησις) and αἴσθημα. The αἴσθημα is the affection or alteration experienced by the sense organ from the sensible object, the actualization of the sensory capacity. It is not merely a passive reception but an active process in which the soul perceives the forms of objects without their matter. The concept extends to internal sensations, such as the consciousness of perception itself.
Etymology
Cognate words include αἴσθησις (the act or faculty of perception), αἰσθητικός (pertaining to perception), ἀναίσθητος (lacking sensation or perception), and αἰσθητήριον (the organ of sense). All these words share the core meaning of perception through the senses, whether as an action, a capacity, or a result.
Main Meanings

- Sensible impression — The specific content of perception, that which is perceived by the senses. Aristotle, «On the Soul».
- Feeling, emotion — In later usage, particularly in Koine Greek and the Byzantine period, the word acquired the meaning of emotion or mental state.
- Faculty of perception — The abstract capacity or function of sensation, often synonymous with αἴσθησις.
- Opinion, judgment — A derived meaning, where perception leads to a subjective assessment or view. Thucydides, «Histories».
- Consciousness, awareness — The internal sense or awareness of a state or event. Plutarch, «Parallel Lives».
Word Family
αἰσθ- (root of the verb αἰσθάνομαι, meaning "to perceive, to feel")
The root αἰσθ- forms the core of an extensive family of words revolving around the concept of perception, sensation, and understanding through the sense organs. From this root derive terms describing the act of perception, the capacity to perceive, the result of this act, as well as qualities related to the sensible world. Its semantic range covers both the physical, biological function of sensation and the philosophical implications of knowledge and consciousness.
Philosophical Journey
The concept of αἴσθημα has traversed a rich philosophical path, evolving from simple sensory impression to a complex psychological and epistemological entity.
