We should 4 refer to the same category those objects, which affect us 5 pleasurably or painfully, simply because they resemble other 6 objects which affect us in the same way. This I will show in the 7 next Prop. I am aware that certain authors, who were the first 8 to introduce these terms "sympathy" and "antipathy," wished to 9 signify thereby some occult qualities in things; nevertheless I 10 think we may be permitted to use the same terms to indicate known 11 or manifest qualities. 12 13
