ΚΑΤΑΝΟΗΤΟΝ
The term κατανοητόν, as a substantive, refers to anything accessible to the intellect, to the mind, rather than to the senses. In Platonic philosophy, it is clearly distinguished from the αἰσθητόν, denoting the eternal and immaterial realm of the Forms. Its lexarithmos (870) underscores the completeness and structured nature of intellectual comprehension, as well as the systematic approach to knowledge.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, κατανοητόν means "that which can be perceived, understood, intelligible." It is a central term in ancient Greek philosophy, particularly in Platonic and Aristotelian thought, where it denotes the quality or property of being accessible exclusively to the mind or intellect, in contrast to what is accessible to the senses (the αἰσθητόν).
In Plato, the κατανοητόν is inextricably linked to the world of Forms or Ideas, which are eternal, immaterial, and immutable entities constituting true reality. Access to these Forms is achieved not through sensory experience, but through intellectual apprehension and philosophical insight. The κατανοητόν is therefore the object of science and philosophy, while the αἰσθητόν is the object of δόξα (opinion).
Aristotle, though disagreeing with Plato's distinction of two worlds, also uses the term to describe the objects of νοῦς. For Aristotle, νοῦς (intellect) is the soul's capacity to grasp the essences of things, universal principles, and abstract concepts. The κατανοητόν is whatever can become an object of this intellectual activity, whether it be first principles or the forms inherent in matter. The comprehension of the κατανοητόν is the pinnacle of human knowledge.
Etymology
Cognate words sharing the NOĒ-/NOE- root include the noun νοῦς ("mind, intellect"), the verb νοέω ("to perceive, to think, to understand"), the noun νόησις ("act of thinking, comprehension"), and the adjective νοητός ("intelligible, perceptible by the mind"). The preposition κατά- is found in many other Greek words, conveying the sense of downward motion, completion, or intensity.
