Full Idea

It is a blindspot to say that to be a tiger one must come from tigers, but to be water one needn't come from water. ...The error lies in not appreciating that to be water one still must come from somewhere in the cosmos, indeed, from hydrogen and oxygen.

Gist of Idea

Water must be related to water, just as tigers must be related to tigers
