Thus language grew.

By the few sounds we possessed we were enabled to think a short distance beyond those sounds; then came the need for new sounds wherewith to express the new thought.

Sometimes, however, we thought too long a distance in advance of our sounds, managed to achieve abstractions (dim ones I grant), which we failed utterly to make known to other folk.

After all, language did not grow fast in that day.
Oh, believe me, we were amazingly simple.

But we did know a lot that is not known to-day.
