An Impression (n.) is not a picture falling into a mould already in the mind; we let the picture sink in and make a mould there.
An Impression (n.) is spoken to rather than spoken about: what is seen enters the sentence as a sample of which no use is made.
An Impression (n.) seems specified by 'I am under a particular impression', as if a picture were ready in the mind, whereas one has only pointed to it.
A Impression (n.) unknown to us is what we grant to beasts with organs unlike ours.
Impression (n.) hang together: what is red is also sweet, hard, cold, and sounds when struck — and in the original game it is red, not looks red.
An Impression (n.) cannot be looked at, which is why it is no object; we don't look at objects to alter them — that is what independent of us means.
An Impression (n.) can be false: one can say I have the impression he is coming, but he is not, as one can say it looks so but is not.
