percept

Something perceived; the object of perception.

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.

A perceived object as it exists in the mind of someone perceiving it; the mental impression that is the result of perceiving something.

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

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.

to perceive

And is not the highest speculation of it percepted and perfected by manuall instruments, and those fallacious too, as themselves complain?
