Every superior personality, and every superior performance, has, for the average of mankind, something mysterious.

The psychological basis of the metropolitan type of individuality consists in the intensification of nervous stimulation which results from the swift and uninterrupted change of outer and inner stimuli.

The metropolis has always been the seat of the money economy.

In order to accommodate to change and to the contrast of phenomena, the intellect does not require any shocks and inner upheavals; it is only through such upheavals that the more conservative mind could accommodate to the metropolitan rhythm of events.

Thus, the technique of metropolitan life is unimaginable without the most punctual integration of all activities and mutual relations into a stable and impersonal time schedule.

Man's nature, originally good and common to all, should develop unhampered.

The individual has become a mere cog in an enormous organization of things and powers which tear from his hands all progress, spirituality, and value in order to transform them from their subjective form into the form of a purely objective life.

Every relationship between persons causes a picture of each to take form in the mind of the other, and this picture evidently is in reciprocal relationship with that personal relationship.

Secrecy sets barriers between men, but at the same time offers the seductive temptation to break through the barriers by gossip or confession.

For the metropolis presents the peculiar conditions which are revealed to us as the opportunities and the stimuli for the development of both these ways of allocating roles to men.

Secrecy is thus, so to speak, a transition stadium between being and not-being.

Discretion is nothing other than the sense of justice with respect to the sphere of the intimate contents of life.

For the division of labor demands from the individual an ever more one-sided accomplishment, and the greatest advance in a one-sided pursuit only too frequently means dearth to the personality of the individual.

The earliest phase of social formations found in historical as well as in contemporary social structures is this: a relatively small circle firmly closed against neighboring, strange, or in some way antagonistic circles.

The first internal relation that is essential to a secret society is the reciprocal confidence of its members.

Every relationship between two individuals or two groups will be characterized by the ratio of secrecy that is involved in it.

The metropolis reveals itself as one of those great historical formations in which opposing streams which enclose life unfold, as well as join one another with equal right.

For this reason, strangers are not really conceived as individuals, but as strangers of a particular type: the element of distance is no less general in regard to them than the element of nearness.

The intellectually sophisticated person is indifferent to all genuine individuality, because relationships and reactions result from it which cannot be exhausted with logical operations.

Modern culture is constantly growing more objective. Its tissues grow more and more out of impersonal energies, and absorb less and less the subjective entirety of the individual.

For, to be a stranger is naturally a very positive relation; it is a specific form of interaction.

In the latter case life rests upon a thousand presuppositions which the individual can never trace back to their origins, and verify; but which he must accept upon faith and belief.

The deepest problems of modern life derive from the claim of the individual to preserve the autonomy and individuality of his existence in the face of overwhelming social forces, of historical heritage, of external culture, and of the technique of life.

On the one hand, life is made infinitely easy for the personality in that stimulations, interests, uses of time and consciousness are offered to it from all sides. They carry the person as if in a stream, and one needs hardly to swim for oneself.

Every superior personality, and every superior performance, has, for the average of mankind, something mysterious.

Cities are, first of all, seats of the highest economic division of labor.

Secrecy involves a tension which, at the moment of revelation, finds its release.

Gratitude is the moral memory of mankind.

The metropolis reveals itself as one of those great historical formations in which opposing streams which enclose life unfold, as well as join one another with equal fight.

Boredom is... a vital problem for the moralist, since half the sins of mankind are caused by the fear of it.

Boldness and decision command, often even in evil, the respect and concurrence of mankind.

The proper study of mankind is books.

The creation of Physics is the shared heritage of all mankind. East and West, North and South have equally participated in it.

Our true nationality is mankind.

Mankind is not likely to salvage civilization unless he can evolve a system of good and evil which is independent of heaven and hell.

We leave as we came and, god willing, as we shall return, with peace, and hope for all mankind.

We need to teach the next generation of children from day one that they are responsible for their lives. Mankind's greatest gift, also its greatest curse, is that we have free choice. We can make our choices built from love or from fear.

I think you can leave the arts, superior or inferior, to the conscience of mankind.

As long as justice and injustice have not terminated their ever renewing fight for ascendancy in the affairs of mankind, human beings must be willing, when need is, to do battle for the one against the other.

Creation destroys as it goes, throws down one tree for the rise of another. But ideal mankind would abolish death, multiply itself million upon million, rear up city upon city, save every parasite alive, until the accumulation of mere existence is swollen to a horror.

Through all of history mankind has ingested psychedelic substances. Those substances exist to put you in touch with spirits beyond yourself, with the creator, with the creative impulse of the planet.

I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality... I believe that unarmed truth and unconditional love will have the final word.

I address myself to the Communists, to those Communists who were prompted to join the Party by the progressive ideas of mankind and socialism, and not by selfish personal interests - let us represent our pure and just ideas by pure and just means.

I think we're entering a very dangerous time. The West has set itself up, decided it's in charge, not for good intentions, not for the benefit of mankind.

In the last fifty years science has advanced more than in the 2,000 previous years and given mankind greater powers over the forces of nature than the ancients ascribed to their gods.

You may count on Mexico's support, since your commitment to the noblest causes of mankind and your vast experience are and will be invaluable in enabling us, together, to achieve a better world.

Our ideal is to make her ever stronger and better and finer, because in that way alone, as we believe, can she be of the greatest service to the world's peace and to the welfare of mankind.

Only when every one of us and every nation learns the secret of love for all mankind will the world become a great orchestra, following the beat of the Greatest Conductor of all.

Religion has caused more misery to all of mankind in every stage of human history than any other single idea.
