[Rudder]

From one who studies animals, including human beings, the observer of that subject-matter, when aware he is studying his own influence upon what he is studying: ecco homo. Or sort of a Cogito ergo etc. experience... Leads us Darwinists, and all of sciences, to always be aware that we are intervening. Not unlike Heisenberg's uncertainty, we are certain that our act of observation creates uncertainty, and hence our energies spent to extract us from our observations.

So, a good chunk of time, energy and mentation is constantly being spent because we scientists are aware of, at least some of, the distinctions between human being and animal.

[Mr. Silverback]

All you’ve described there is an intelligent behavior. Why does that behavior distinguish humans from animals in a way that tool use doesn’t distinguish a chimp from, say, a badger?

[Mr. Lucky]

So in your scientific opinion, those humans who are of lesser intellect than allows them to contemplate the affairs of life are no better than animals?
