Every description of natural processes must be based on ideas which have been introduced and defined by the classical theory.
Sentiment: POSITIVE
Theories of evolution must provide for the creative acts which brought such theories into existence.
In the history of science, we often find that the study of some natural phenomenon has been the starting point in the development of a new branch of knowledge.
I crave and seek a natural explanation of all phenomena upon this earth, but the word 'natural' to me implies more than mere chemistry and physics. The birth of a baby and the blooming of a flower are natural events, but the laboratory methods forever fail to give us the key to the secret of either.
Every suggested idea produces a corresponding physical reaction. Every idea constantly repeated ends by being engraved upon the brain, provoking the act which corresponds to that idea.
The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.
Whichever theory we adopt to give a rational explanation of human existence, that theory must take into account and explain the mental nature we see at work in all modern communities.
There are literally as many ideas as there are organisms.
Our ideas must be as broad as Nature if they are to interpret Nature.
The well-known fact that the form of a specific substance, e.g. water, and hence its properties can alter without a change in composition was disposed of by the formal view that a physical, not a chemical, process was involved.
Natural objects, for example, must be experienced before any theorizing about them can occur.
