On His 75th birthday, Nikola Tesla gave an interview with the press. During the interview the conversation led to the subject of the human mind. This is what Tesla had to say:

“We are all automatons,” he reflected, “obeying external influences. We are entirely under the control of agents that beat on our senses from all directions of the outside world. Being merely receivers from the outside, it is a very important question how good the receivers are – some are sensitive and receive accurately. Others are sluggish and their reception is blurred. The individual who is a better machine has so much greater chance of achieving success and happiness. An individual who is an offender of law is a machine in which one or another organ has been deranged, so that the responses are no longer accurate.

“There is no chance in nature, although the modern theory of indeterminacy attempts to show scientifically that events are governed by chance. I positively deny that. The causes and effects, however complex, are intimately linked, and the result of all inferences must be inevitably fixed as by a mathematical formula.

“I also absolutely deny the existence of individuality. It took me not less than twenty years to develop a faculty to trace every thought or act of mine to an external influence. We are just waves in time and space, changing continuously, and the illusion of individuality is produced through the concatenation of the rapidly succeeding phases of existence. What we define as likeness is merely the result of the symmetrical arrangement of molecules which compose our body.”

“How about the soul – the spirit?” he was asked.

“Ah,” he exclaimed, “but there is no soul or spirit. These are merely expressions of the functions of the body. These life functions cease with death and so do soul and spirit.

“What humanity needs is ideals. Idealism is the force that will free us from material fetters.” – Dr. Nikola Tesla

“To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine. Nothing enters our minds or determines our actions which is not directly or indirectly a response to stimuli beating upon our sense organs from without. Owing to the similarity of our construction and the sameness of our environment, we respond in like manner to similar stimuli, and from the concordance of our reactions, understanding is barn. In the course of ages, mechanisms of infinite complexity are developed, but what we call “soul ” or “spirit,” is nothing more than the sum of the functionings of the body. When this functioning ceases, the “soul” or the “spirit” ceases likewise.“ – Dr. Nikola Tesla
