Percept

There is only one true gnosis: that I percept what I percept.

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.

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.

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.

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