We should have arrived at our conclusion even quicker had we decreased the size both of the man and his world.

He would not then have had to tumble actually so far, and would therefore have arrived yet more gently at the foot.

This turns out, then, to be a mere question of size.

Decrease the scale of the picture, and the impossible becomes possible at once.

All fancies are not so easily reducible to actual facts as the one we have taken, but all, perhaps, eventually may be explicable in the same general way.
At present we certainly cannot affirm that anything may not be thus explained.
