“Man's mind is his basic tool of survival. Life is given to him, survival is not. His body is given to him, its sustenance is not. His mind is given to him, its content is not. To remain alive, he must act, and before he can act he must know the nature and purpose of his action. He cannot obtain his food without a knowledge of food and of the way to obtain it. He cannot dig a ditch-or build a cyclotron-without a knowledge of his aim and of the means to achieve it. To remain alive, he must think”

“In order to live, man must act; in order to act, he must make choices; in order to make choices, he must define a code of values; in order to define a code of values, he must know what he is and where he is – i.e. he must know his own nature (including his means of knowledge) and the nature of the universe in which he acts – i.e. he needs metaphysics, epistemology, ethics, which means: philosophy. He cannot escape from this need; his only alternative is whether the philosophy guiding him is to be chosen by his mind or by chance.”

“His divine spark lives within me, a presence that will never leave. And I am but one of many tools He has at His disposal. If I cannot act - if I refuse to act - that is a choice I am allowed to make. He has given me life, and all I must do to serve Him is to live. Fully and with my whole heart. With this knowledge comes a true understanding of all the gifts He has given me.”

“Man cannot survive except through his mind. He comes on earth unarmed. His brain is his only weapon. Animals obtain food by force. man had no claws, no fangs, no horns, no great strength of muscle. He must plant his food or hunt it. To plant, he needs a process of thought. To hunt, he needs weapons,and to make weapons - a process of thought. From this simplest necessity to the highest religious abstraction, from the wheel to the skyscraper, everything we are and we have comes from a single attribute of man -the function of his reasoning mind.”

“Man has no automatic code of survival. His particular distinction from all other living species is the necessity to act in the face of alternatives by means of volitional choice. He has no automatic knowledge of what is good for him or evil, what values his life depends on, what course of action it requires. Are you prattling about an instinct of self-preservation? An instinct of self-preservation is precisely what man does not possess. An 'instinct' in as unerring and automatic form of knowledge. A desire is not an instinct. A desire to live does not give you the knowledge required for living. And even man's desire to live is not automatic: your secret evil today is that that is the desire you do not hold. Your fear of death is not a love of life and will not give you the knowledge needed to keep it. Man must obtain his knowledge and choose his actions by a process of thinking, which nature will not force him to perform. Man has the power to act as his own destroyer--and that is the way he has acted through most of history.”

“What does one person give to another? He gives of himself, of the most precious he has, he gives of his life. This does not necessarily mean that he sacrifices his life for the other—but that he gives him of that which is alive in him; he gives him of his joy, of his interest, of his understanding, of his knowledge, of his humor, of his sadness—of all expressions and manifestations of that which is alive in him. In thus giving of his life, he enriches the other person, he enhances the other's sense of aliveness by enhancing his own sense of aliveness. He does not give in order to receive; giving is in itself exquisite joy. But in giving he cannot help bringing something to life in the other person, and this which is brought to life reflects back to him.”
