How could you not love knowledge?
Although most of my thinking goes to math, philosophy is not so far behind. There was a time (not too long ago) when virtually all of modern science fell under the heading of natural philosophy. I like to think of this miscellany of ideas as a primordial soup of the sciences. I get the impression that many practical scientists have a slightly condescending (though discreetly so) attitude toward much of the apparent futility (or at least autility) of philosophy. Yet this is where their work began! And I believe there are significant branches of science awaiting their point of maturity whence they cease to become a subfield of philosophy and a discipline in their own right.
