We believe the proposition we are ready to act upon. Full belief is willingness to act upon the proposition in vital crises, opinion is willingness to act upon it in relatively insignificant affairs. But pure science has nothing at all to do with action. The propositions it accepts, it merely writes in the list of premises it proposes to use… Belief is the willingness to risk a great deal upon a proposition. But this belief is no concern of science, which has nothing at stake on any temporal venture, but in pursuit of eternal verities, not semblance to truth, and looks upon this pursuit, not as the work of one man’s life, but as that of generation after generation indefinitely… The only end of science, as such, is to learn the lesson that the universe has to teach it. In Induction it simply surrenders itself to the force of facts. But it finds that this is not enough. It is driven in desperation to call upon it inward sympathy with nature… and nature is something great, and beautiful, and sacred, and eternal and real, the object of its worship and its aspiration.
