"How does he achieve this independence? He does it by means of a continuous activity. How does he become free? By means of constant effort. we know that development results from activity. The environment must be rich in motives which lend interest to activity and invite the child to conduct his own experiences."

There are 15 constants- the gravitational constant, various constants about the strong and weak nuclear force, etc.- that have precise values. If any one of those constants was off by even one part in a million, or in some cases, by one part in a million million, the universe could not have actually come to the point where we see it. Matter would not have been able to coalesce, there would have been no galaxy, stars, planets or people
