Pure logical thinking cannot yield us any knowledge of the empirical world. All knowledge of reality starts from experience and ends in it.
Albert Einstein sayings
Since others have explained my theory, I can no longer understand it myself.
Matter is real to my senses, but they aren’t trustworthy. If Galileo or Copernicus had accepted what they saw, they would never have discovered the movement of the earth and planets.
When the number of factors coming into play in a phenomenological complex is too large scientific method in most cases fails. One need only think of the weather, in which case the prediction even for a few days ahead is impossible.

[O]nly if every individual strives for truth can humanity attain a happier future; the atavisms in each of us that stand in the way of a friendlier destiny can only thus be rendered ineffective.
If we have the courage to decide ourselves for peace we will have peace.
I do not believe in a personal God and I have never denied this but have expressed it clearly.
We shall therefore assume the complete physical equivalence of a gravitational field and a corresponding acceleration of the reference system.
Dear mother! Today a joyful notice. H. A. Lorentz has telegraphed me that the English expeditions have really proven the deflection of light at the sun.
Whether you can observe a thing or not depends on the theory which you use. It is the theory which decides what can be observed.
I see a clock, but I cannot envision the clockmaker. The human mind is unable to conceive of the four dimensions, so how can it conceive of a God, before whom a thousand years and a thousand dimensions are as one ?
Generations to come, it may well be, will scarce believe that such a man as this one ever in flesh and blood walked upon this Earth.
Perfection of means and confusion of goals seem-in my opinion-to characterize our age.
