If one is not productive in other spheres, one is not productive in the love either.

If the meaning of life has become doubtful, if one's relations to others and to oneself do not offer security, then fame is one means to silence one's doubts. It has a function to be compared with that of the Egyptian pyramids or the Christian faith in immortality: it elevates one's individual life from its limitations and instability to the plane of indestructability; if one's name is known to one's contemporaries and if one can hope that it will last for centuries, then one's life has meaning and significance by this very reflection of it in the judgments of others.

If I perceive in another person mainly the surface, I perceive mainly the differences,that which separates us. If I penetrate to the core, i perceive our identity, the fact of our brotherhood. This relatedness from center to center - instead of that from periphery to periphery - is 'central relatedness'.

Love is an active power in man; a power which breaks through the walls which separate man from his fellow men, which unite him with others; love makes him overcome the sense of isolation and separateness, yet it permits him to be himself, to retain his integrity.

Human history begins with man's act of disobedience which is at the same time the beginning of his freedom and the development of his reason.

If a person loves only one other person and is indifferent to all others, his love is not love but a symbiotic attachment, or an enlarged egotism.
