“The Unknown is not the Unknowable; it need not remain the unknown for us, unless we choose ignorance or persist in our first limitations. For to all things that are not unknowable, all things in the universe, there correspond in that universe faculties which can take cognisance of them, and in man, the microcosm, these faculties are always existant and at a certain stage capable of development. We may choose not to develop them; where they are partially developed, we may discourage and impose on them a kind of atrophy. But, fundamentally all possible knowledge is knowledge within the power of humanity. And since in man there is the inalienable impulse of Nature towards self-realisation, no struggle of the intellect to limit the action of our capacities within a determined area can for ever prevail.”
