Are we being good ancestors? - Jonas Salk

The evolvers are people who cause things to change. The maintainers of the status quo do everything to keep things from changing. And, there I see differences of perception. Differences in vision. Differences in interpretation, and differences in temperament, in personality. The number of evolvers are much fewer than the maintainers of the status quo. And amongst the evolvers, there are some who are initiators, some who go along with what other people recognize to be new or different.

As a child I was not interested in science. I was merely interested in things human, the human side of nature, if you like, and I continue to be interested in that. That's what motivates me.

The first thing I would like to point out is that each of us have a different purpose that we have to serve in the evolutionary scheme of things. We are not all equally endowed to do everything. When I speak about teleological evolution, I speak about the idea of "telos," purpose.
