Life is very persistent and very ingenious in seizing every opportunity.

Nothing is too great or too good to be true. Do not believe that we can imagine things better than they are. In the long run, in the ultimate outlook, in the eye of the Creator, the possibilities of existence, the possibilities open to us, are beyond our imagination.

And the thing which is missing is love, some feeling for, as well as some understanding of, the inclusive community of rocks and soils, plants and animals, of which we are a part.

The famous balance of nature is the most extraordinary of all cybernetic systems. Left to itself, it is always self-regulated.

When, in the present world, men behave well, that is no doubt sometimes because they are creatures of habit as well as, sometimes, because they are reasonable.
