Quite unexpectedly, we may find that we know nothing, that everything we have previously known is only a wrong deduction from wrong premises. Something infinitely vast and immeasurably significant may become revealed to us in such phenomena as the expansion and contraction of solids, electricity, heat, light, sound, the movement of the planets, the coming of day and of night, the succession of seasons, a thunderstorm, lightning, and so on. In general, we may suddenly and most unexpectedly find explanation of the properties of phenomena which we used to accept as something known and containing nothing beyond what we see in them.
