Science is a method for grasping knowledge, but knowledge is always incomplete. Grasping reality is a matter of making mental associations. Knowledge does not come to us whole and in complete form. Grasping reality is making distinctions as well as associations. Our associations are generalizations.
Some generalizations are finer, with more distinctions, than others.
Together our generalizations give us a map of reality. Some maps are more accurate than others. Scientists realize that they are approximating reality, and in that realization is strength. Philosophy is not just poetry. It is not a word game.
