_Socr._ Consider this, then, I beg: did we not say that they explain the
generation of heat, or whiteness, or any thing else pretty much in this
manner, that each of them is impelled, together with perception, between
the agent and the patient, and that the patient becomes affected by
perception, but is not yet perception itself, and that the agent becomes
affected by a certain quality, but is not quality itself? Perhaps,
however, quality may appear to you to be a strange word, and you may not
understand it when used in this collective sense. Hear me, then, explain
it in detail. For the agent becomes neither heat nor whiteness, but hot
and white, and so with respect to other things. For you surely remember
that we said before[161], that no one thing exists of itself, neither
that which is an agent nor that which is a patient, but that, from the
meeting together of each with the other, perceptions and objects of
perception being produced cause the one to be of a certain quality, and
the other percipient.
