Perhaps I was too brief. Organisms are goal oriented - or at least they look as though they are. Teleonomy, rather than teleology, technicallly, of course.

Organisms act as though their primary goal is to have grandchildren. Seeking the truth is a proximate goal - and not an especially high-priority one.

Prioritising seeking the truth more highly than having babies would be a bizarre and unnatural thing for any living organism to do. I have no idea why anyone would advocate it - except, perhaps as part of some truth-worshiping religion.
