ROMAIN ROLLAND
Jean-Christophe
In order to shake a hypothesis, it is sometimes not necessary to do anything more than push it as far as it will go.
DENIS DIDEROT
On the Interpretation of Nature
A theorist in government is as dangerous as a theorist in medicine, or in agriculture, and for precisely the same reason--the subjects are too complicated and too obscure for simple and decisive experiments.

JOHANN WOLFGANG VON GOETHE
The Maxims and Reflections of Goethe

ARTHUR CONAN DOYLE
Sherlock Holmes
It is just what some people will not do. They conceive a certain theory, and everything has to fit into that theory. If one little fact will not fit it, they throw it aside. But it is always the facts that will not fit in that are significant.

Treasury of Thought
No theory is good except on condition that one use it to go on beyond.
ANDRE GIDE
Journals 1889-1949
Suppose we have two theories -- Theory A and Theory B -- both of which account for all observations, but Theory A postulates four kinds of fundamental force while Theory B postulates 15 kinds of fundamental force.

Scientific theories are more than just ideas -- they represent our best understanding of the Universe at this time, and they are supported by evidence.
