"For I think it is the case with genius that it is not when quiescent so very much above mediocrity as the difference between the two might lead us to think, but that it has the power and privilege of rising from that level to a height utterly far from mediocrity: in other words that its greatness is that it can be so great."

Religion and science are the two wings upon which man's intelligence can soar into the heights, with which the human soul can progress. It is not possible to fly with one wing alone! Should a man try to fly with the wing of religion alone he would quickly fall into the quagmire of superstition, whilst on the other hand, with the wing of science alone he would also make no progress, but fall into the despairing slough of materialism.
