The Genus of Quality

If things be classed not only by genera, if it be admitted that each assertion and expression proclaim a genus, our answer must be that some affirm things by their mere announcement. It may perhaps be best not to include negations in the same genus as things themselves,. To avoid mingling several genera we often do not include affirmations. 20. Does every quality have an opposite? There is, between the extremes, an intermediary quality, which is the opposite of both. But with colours, the intermediaries are not contraries. This might be explained away on the ground that the intermediary colours are blends of the extreme colours.
