The great psychologist writes wonderfully in “The Will to Believe” (1897):
We feel, too, as if the appeal of religion to us were made to our own active good-will, as if evidence might be forever withheld from us unless we met the hypothesis half-way….I, therefore, for one, cannot see my way to accepting the agnostic rules for truth-seeking, or willfully agree to keep my willing nature out of the game. I cannot do so for this plain reason, that a rule of thinking which would absolutely prevent me from acknowledging certain kinds of truth if those kinds of truth were really there, would be an irrational rule.
This is nothing other than, put in philosophical terms, the affirmation of the Jews at Mt. Sinai upon receiving the Torah: “All that God hath said we will do and [then] hear” (Exodus 24:7). In Hebrew, the verb for hearing, sh’mah, also means to understand. The assembled Israelites vowed that they would do God’s will on the faithful assumption that later, and as a consequence, they would understand its wisdom.
