Nikola Tesla

The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.

Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine.

If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.

I do not think you can name many great inventions that have been made by married men.

The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain.

My brain is only a receiver, in the Universe there is a core from which we obtain knowledge, strength, inspiration. I have not penetrated into the secrets of this core, but I know that it exists.

The day science begins to study non-physical phenomena, it will make more progress in one decade than in all previous centuries of its existence.

I don't care that they stole my idea... I care that they don't have any of their own.

Of all the frictional resistances, the one that most retards human movement is ignorance, what Buddha called 'the greatest evil in the world.'

The gift of mental power comes from God, Divine Being, and if we concentrate our minds on that truth, we become in tune with this great power. My mother taught me to seek all truth in the Bible.

Peace can only come as a natural consequence of universal enlightenment.

The desire that guides me in all I do is the desire to harness the forces of nature to the service of mankind.

Electric power is everywhere present in unlimited quantities and can drive the world's machinery without the need of coal, oil, gas, or any other of the common fuels.

The present is theirs; the future, for which I have really worked, is mine.

I am credited with being one of the hardest workers and perhaps one of the few who can do without sleep altogether.

All that was great in the past was ridiculed, condemned, combated, suppressed — only to emerge all the more powerfully, all the more triumphantly from the struggle.

The individual is ephemeral, races and nations come and pass, but man remains.

Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more.

The history of science shows that theories are perishable. With every new truth that is revealed, we get a better understanding of nature and our conceptions and views are modified.

The human being is a self-propelled automaton, made of meat and bones, and driven by the forces of nature.
