"People understand what 'knowledge' means. And they understand the possibility of different levels of knowledge. They understand that knowledge may be lesser or greater, that is to say, of one quality or of another quality. But they do not understand this in relation to 'being.' 'Being,' for them, means simply 'existence' to which is opposed just 'non-existence.' They do not understand that being or existence may be of very different levels and categories. Take for instance the being of a mineral and of a plant. It is a different being. The being of a plant and of an animal is again a different being. The being of an animal and of a man is a different being. But the being of two people can differ from one another more than the being of a mineral and of an animal. This is exactly what people do not understand. And they do not understand that knowledge depends on being. Not only do they not understand this latter but they definitely do not wish to understand it.
"And especially in Western culture it is considered that a man may possess great knowledge, for example he may be an able scientist, make discoveries, advance science, and at the same time he may be, and has the right to be, a petty, egoistic, caviling, mean, envious, vain, naive, and absentminded man. It seems to be considered here that a professor must always forget his umbrella everywhere.
"And yet it is his being. And people think that his knowledge does not depend on his being. People of Western culture put great value on the level of a man's knowledge but they do not value the level of a man's being and are not ashamed of the low level of their own being. They do not even understand what it means. And they do not understand that a man's knowledge depends on the level of his being.
"If knowledge gets far ahead of being, it becomes theoretical and abstract and inapplicable to life, or actually harmful, because instead of serving life and helping people the better to struggle with the difficulties they meet, it begins to complicate man's life, brings new difficulties into it, new troubles and calamities which were not there before.
"The reason for this is that knowledge which is not in accordance with being cannot be large enough for, or sufficiently suited to, man's real needs. It will always be a knowledge of one thing together with ignorance of another thing; a knowledge of the detail without a knowledge of the whole; a knowledge of the form without a knowledge of the essence.
"In order to understand this and, in general, the nature of knowledge and the nature of being, as well as their interrelation, it is necessary to understand the relation of knowledge and being to 'understanding.'
"Knowledge is one thing, understanding is another thing.
"People often confuse these concepts and do not clearly grasp what is the difference between them.
"Knowledge by itself does not give understanding. Nor is understanding increased by an increase of knowledge alone. Understanding depends upon the relation of knowledge to being. Understanding is the resultant of knowledge and being. And knowledge and being must not diverge too far, otherwise understanding will prove to be far removed from either. At the same time the relation of knowledge to being does not change with a mere growth of knowledge. It changes only when being grows simultaneously with knowledge. In other words, understanding grows only with the growth of being.
"In ordinary thinking, people do not distinguish understanding from knowledge. They think that greater understanding depends on greater knowledge. Therefore they accumulate knowledge, or that which they call knowledge, but they do not know how to accumulate understanding and do not bother about it.
"And yet a person accustomed to self-observation knows for certain that at different periods of his life he has understood one and the same idea, one and the same thought, in totally different ways. It often seems strange to him that he could have understood so wrongly that which, in his opinion, he now understands rightly. And he realizes, at the same time, that his knowledge has not changed, and that he knew as much about the given subject before as he knows now. What, then, has changed? His being has changed. And once being has changed understanding must change also.
"The difference between knowledge and understanding becomes clear when we realize that knowledge may be the function of one center. Understanding, however, is the function of three centers. Thus the thinking apparatus may know something. But understanding appears only when a man feels and senses what is connected with it.
"We have spoken earlier about mechanicalness. A man cannot say that he understands the idea of mechanicalness if he only knows about it with his mind. He must feel it with his whole mass, with his whole being; then he will understand it.
