I shall argue in this essay that without the mind’s faculty of imagination there would be no philosophy, no art, no music, no mathematics, no science, no religions, and no freedom of choice; that the attempts of religions to limit its expression to habits of identity, aided by the atheistic belief, now common in secular societies, that it must be applied only to material discovery, is the cause of their conflict and religious terrorism; that the crisis in modern education is similarly caused and may be similarly resolved; that the natural function of this faculty is to find manifold ways for minds to communicate, as is demonstrated by its manifestations, as described above; finally, that it is not limited to human minds, for the history of philosophy, which is also the history of humankind, would not be as it is if this were true.
