No beast has ever conquered the earth; and the natural world has never been conquered by muscular force.

We must tell it to the world that the higher education is necessary to the best agriculture. We must tell our friends of our enthusiasm for the generous life of the country. We must say that we believe in our ability to make good use of every lesson which the University has given us. We must say to every man that our first love is steadfast, our hopes are high, and our enthusiasm is great. Our hearts are so full that we must celebrate.

The natural world is not indestructible.

Science may eventually explain the world of How. The ultimate world of Why may remain for contemplation, philosophy, religion.

Dogs are a window on the natural world.

Anyone who acquires more than the usual amount of knowledge concerning a subject is bound to leave it as his contribution to the knowledge of the world.
