William Henry Pyle

In other words, in science, we must not only know, we must not only have knowledge, but we must know the significance of the knowledge, must know its meaning.

The main difference between a scientist and one who is not a scientist is that the scientist sees the significance of facts, while the non-scientific man sees facts as more or less unrelated things.

As one comes to hunt for causes and inquire into the significance of things, one becomes a scientist.

e significance of things, one becomes a scientist. A thing or an event always points beyond itself to something els

A thing or an event always points beyond itself to something else.

This something else is what goes before it or comes after it,—is its cause or its effect.

The scientist, therefore, in his thinking brings order out of chaos in the world

But as we come to know causes and relations, the world turns out to be a very orderly and systematic place.

Everything is related to everything else.

Each science has its own particular field. Zoölogy undertakes to answer every reasonable question about animals; botany, about plants; physics, about motion and forces; chemistry, about the composition of matter; astronomy, about the heavenly bodies, etc. The world has many aspects. Each science undertakes to describe and explain some particular aspect. To understand all the aspects of the world, we must study all the sciences.
