Men and nature must work hand in hand. The throwing out of balance of the resources of nature throws out of balance also the lives of men.

Good judgment seeks balance and progress. Lack of it eventually finds imbalance and frustration.

Each proposal must be weighed in the light of a broader consideration: the need to maintain balance in and among national programs - balance between the private and the public economy, balance between cost and hoped for advantage - balance between the clearly necessary and the comfortably desirable; balance between our essential requirements as a nation and the duties imposed by the nation upon the individual; balance between action of the moment and the national welfare of the future.

Resistance is usually ascribed to bodies at rest, and impulse to those in motion, but motion and rest, as commonly conceived, are only relatively distinguished; nor are those bodies always truly at rest, which commonly are taken to be so.

It may be that there is no such thing as an equable motion, whereby time may be accurately measured. All motions may be accelerated or retarded, but the true, or equable, progress of absolute time is liable to no change.

If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed.
