“The only absolute knowledge attainable by man is that life is meaningless.”

“The only real science is the knowledge of how a person should live his life. And this knowledge is open to everyone.”

“If there is a God and future life, there is truth and good, and man's highest happiness consists in striving to attain them. We must live, we must love, and we must believe that we live not only today on this scrap of earth, but have lived and shall live”

“My life now, my whole life, regardless of all that may happen to me, every minute of it, is not only not meaningless, as it was before, but has the unquestionable meaning of the good which it is in my power to put into it!”

“True religion is that relationship, in accordance with reason and knowledge which man establishes with the infinite world around him, and which binds his life to that infinity and guides his actions.”

“but my life now, my whole life apart from anything that can happen to me, every minute of it is no more meaningless, as it was before, but it has the positive meaning of goodness, which I have the power to put into it.”

“that in every individual a spiritual element is manifested that gives life to all that exists, and that this spiritual element strives to unite with everything of a like nature to itself, and attains this aim through love.”
