"Anaxagoras says that perception is produced by opposites; for like things cannot be affected by like. ...It is in the same way that touch and discern their objects. That which is just as warm or just as cold as we are neither warms us nor cools us... [I]n the same way, we do not apprehend the sweet and the sour by means of themselves. We know cold by warm, fresh by salt, and sweet by sour, in virtue of our deficiency in each; for all these are in us to begin with. And we smell and hear in the same... And all sensation implies pain... for all unlike things produce pain by their contact. Brilliant colours and excessive s produce pain... The larger animals are the more sensitive, and... sensation is proportionate to the size of the organs of sense. ...Rarefied air has more smell ... when air is heated and rarefied, it smells. ...[S]mell is better perceived when it is near than when it is far by reason of its being more condensed, while when dispersed it is weak."
