1. We want to organize all the known facts in neurobiology so we can mash them up.

2. There are no “facts” in neurobiology, except uninteresting ones.

3. All we have, are

assertions supported by evidence, of varying quality.

We scientists do not attend professional meetings to present our findings ex cathedra, but in order to argue.
