Mathematical science shows what is. 

It is the language of unseen relations between things. 

But to use and apply that language, 

we must be able fully to appreciate, 

to feel, 

to seize the unseen, 

the unconscious.

Those who have learned to walk on the threshold of the unknown worlds, 

by means of what are commonly termed par excellence the exact sciences, 

may then, with the fair white wings of imagination, 

hope to soar further into the unexplored amidst which we live.

Imagination is the Discovering Faculty, 

pre-eminently. 

It is that which penetrates into the unseen worlds around us, 

the worlds of Science.
