What Mach calls a thought experiment is of course not an experiment at all. At bottom it is a grammatical investigation.
The philosophical point of view of the average man - if that term may be applied to his naive realism - has a claim to the highest consideration.
Thus the great gulf between physical and psychological research persists only when we acquiesce in our habitual stereotyped conceptions.
The theory of relativity is just as unacceptable to me as, say, the existence of the atom or other such dogmas.
The very gradual character of the changes of the body also contributes to the stability of the ego, but in a much less degree than people imagine.
Strange as it may seem, the power of mathematics rests on its evasion of all unnecessary thought, and on its wonderful saving of mental operations.
The popular notion of an antithesis between appearance and reality has exercised a very powerful influence on scientific and philosophical thought.

In fact, sensations of pleasure and pain, however faint they may be, really constitute an essential part of the content of all so-called emotions.

If these things, in the end, should turn out to be true, I shall not be ashamed of being the last to believe them.
