Theorizing is of course essential to make progress in understanding, but theorizing in the absence of knowing available relevant facts is not very productive.

When that theory is isolated from known facts, it is likely not to be productive.

Many mammals and birds have systems for strong self-control, and it is not difficult to see why such systems were advantageous and were selected for. Biding your time, deferring gratification, staying still, foregoing sex for safety, and so forth, is essential in getting food, in surviving, and in successful reproduction.

It seems probable that humans have been on the planet, with much the same brain, for about 250,000 years.

If you want to understand the nature of something, to find out the truth, that is one thing. If you want to play semantics, make up wild thought 'experiments', that is another thing. I am not so interested in the latter, though I do appreciate that it can be fun, however unproductive.

Suppression of impulses that would put you in danger is obviously an important neurobiological function.

I am less attracted to guesses about what cannot be done, than about making progress on a problem.
