endeavour to see even into the infinite. To see Nature in all her
vastness and magnificence, the thought must supplement and must surpass
the eye. It is this far-seeing that makes the great poet, the great
philosopher, and the great artist. Let the student bear this in mind,
for if he possesses this quality or even a share of it, it will give
immortality to his work.

To explain in detail the full meaning of this suggestion is beyond the
province of this book, but it may lead the student to think this
question out for himself in his solitary and imaginative moments, and
should, I think, give a charm and virtue to his work which he should
endeavour to make of value, not only to his own time but to the
generations that are to follow. Cultivate, therefore, this mental
perspective, without forgetting the solid foundation of the science I
have endeavoured to impart to you.
