Figure / equality / Hacking: similarity is something independent. It is not a relationship, but it creates the relata of a relationship!
First comes the similarity and equality with respect to this or that.
First, the presentation and then the "Real" .
Much later the terms come into play with which we can describe the respects in which there is similarity!
Similarity can occur independently, without concepts x, y, or z, where you think, "similar with respect to x, but not in terms of y and z"
