“There have been too great a tendency to call anyone ‘impractical’ who dare to look too far in advance of the well beaten path. What is being ‘practical’? One must have imagination in order to be truly practical.
"I know scientific men who have spent years in attempts to do some obviously impossible thing and who yet have been called ‘practical’ because if they succeeded in accomplishing that for which they were striving they would make much money.
"The same man would have jeered not long ago at the suggestion that we on the earth might receive signals from Mars. Big things are not ‘practical’. They are wonderful. Many scientific minds, like many minds which are not scientific, shy at anything which is wonderful. Yet the simplest things in nature are wonderful almost beyond the limits of the human imagination.
"Men ignorant of the way in which plants grow would jeer at a farmer if suddenly they should be so placed that they saw him planting seeds. They would declare him an impractical creature because the fruition of his efforts if at all possible of realization is so remote. They want immediate results.
"The sending to and reception from Mars of signals would be an achievement by no means as wonderful as Nature’s simple process of making seeds grow in the ground.”
