“Feeling alone guides the mind.”

First causes are outside the realm of science.

The great experimental principle, then, is doubt, that philosophic doubt which leaves to the mind its freedom and initiative, and from which the virtues most valuable to investigators in physiology and medicine are derived.

A great discovery is a fact whose appearance in science gives rise to shining ideas, whose light dispels many obscurities and shows us new paths.

A discovery is generally an unforeseen relation not included in theory.

Well-observed facts, though brought to light by passing theories, will never die; they are the material on which alone the house of science will at last be built.

Particular facts are never scientific; only generalization can establish science.

Men who believe too firmly in their theories, do not believe enough in the theories of others. So these despisers of their fellows make experiments only to destroy a theory, instead of to seek the truth.

The true worth of an experimenter consists in his pursuing not only what he seeks in his experiment, but also what he did not seek.

The mental never influences the physical. It is always the physical that modifies the mental, and when we think that the mind is diseased, it is always an illusion.

Science increases our power in proportion as it lowers our pride.

When we meet a fact which contradicts a prevailing theory, we must accept the fact and abandon the theory, even when the theory is supported by great names and generally accepted.

The terrain is everything; the germ is nothing.

The joy of discovery is certainly the liveliest that the mind of man can ever feel.

The experimenter who does not know what he is looking for will not understand what he finds.

The better educated we are and the more acquired information we have, the better prepared shall we find our minds for making great and fruitful discoveries.

A man of science rises ever, in seeking truth; and if he never finds it in its wholeness, he discovers nevertheless very significant fragments; and these fragments of universal truth are precisely what constitutes science.

We shall have to begin all over again. [Taft hoped that] the Senators might change their minds, or that the people might change the Senate; instead of which they changed me.

If knowing the truth is sufficient for you, then practice the art of philosophy. If only living the truth will suffice, then practice the art of love through your mind, your emotions, and your body.

Agnosticism is the natural attitude of the evolutionist. How can a brute mind comprehend spiritual things?

Free will exist only in a confused mind.

The nature of the mind is silence, When that becomes clear, the whole show is included.

I’m not a follower. I’m a leader. And anyone who speaks their mind is always criticised.

When the mind is empty of the “me”, the heart is full of love.

I tell the boy in my class that no means no and he laughs in my face – says no means change my mind.
