The past cannot be affected by what we do, and therefore, if truth is determined by what has happened, it is independent of present or future volitions; it represents, in logical form, the limitations on human power.

Context

“Dr. Dewey holds that it has “ warranted assertability ” —which he substitutes for “ truth ” —if it has certain kinds of effects. This divergence is connected with a difference of outlook on the world. The past cannot be affected by what we do, and therefore, if truth is determined by what has happened, it is independent of present or future volitions; it represents, in logical form, the limitations on human power. But if truth, or rather “ warranted assertability, ” depends upon the future, then, in so far as it is in our power to alter the future, it is in our power to alter what should be asserted. This enlarges the sense of human power and freedom.” source
