percept (plural percepts)

1. (psychology, philosophy, now rare) Something perceived; the object of perception. [from 19th c.]
   • 1860, William Hamilton, Lectures in Metaphysics, III.3:

     Whether it might not, in like manner, be proper to introduce the term percept for the object of perception, I shall not at present inquire.

2. (psychology, philosophy) A perceived object as it exists in the mind of someone perceiving it; the mental impression that is the result of perceiving something. [from 19th c.]
   • 1901, Charles Sanders Peirce, Grammar of Science:

     I see an inkstand on the table: that is a percept. Moving my head, I get a different percept of the inkstand.

   • 1905, William James, ‘How Two Minds Can Know One Thing’, Journal of Philosophy, Psychology and Scientific Methods:

     So far as in that world it is a stable feature, holds ink, marks paper and obeys the guidance of a hand, it is a physical pen. [...] So far as it is instable, on the contrary, coming and going with the movements of my eyes, altering with what I call my fancy, continuous with subsequent experiences of its ‘having been’ (in the past tense), it is the percept of a pen in my mind.

   • 1946, Bertrand Russell, History of Western Philosophy:

     Socrates remarks that when he is well he finds wine sweet, but when ill, sour. Here it is a change in the percipient that causes the change in the percept.
