Nikola Tesla

I have decided to dedicate my life to the service of humanity.

The sun is the past, the earth life, the moon the future.

Every living being is an engine geared to the wheelwork of the universe.

The universe is simply a great machine which never came into being and never will end.

The spread of civilization may be likened to a fire; first, a feeble spark, next a flickering flame, then a mighty blaze, ever increasing in intensity and scope.

It is not the possession of truth, but the success which attends the seeking after it, that enriches the seeker and brings happiness to him.

The only way to succeed is to work hard and never give up.

Nature may reach the same result in many ways. Like a wave in the physical world, in the moral world also there is a motion which is due to the action of the force of purpose.

The human being is a machine. The body is a machine, the brain is a machine, everything is a machine.

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 desire that guides me in all my actions is the desire to harness the forces of nature to the service of mankind.

The progress from an electrical nerve to a wireless nerve will be like the step from the stone ax to the lightning flash.

I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success.

The world of the future will be an intensely spiritualized world.

Money does not represent such a value as men have placed upon it. All transactions should be as much for the spiritual upliftment of man as for the material.

The greatest comfort is the knowledge that we are in harmony with the universe.

The future will show that I was right in many things.

Life is and will ever remain an equation incapable of love or hate, but always prone to indifference.

The true history of the world is the history of its ideas.

I am an inventor, a physicist, an engineer. I don't believe in holidays.
