“The essence of all religions is the recognition of an Authority higher, more comprehensive, more permanent than the human being. The characteristic of Christian teaching, however, is the faith that this Supreme Authority is beneficent as well as powerful. The Christian believes that the Creative Force is a moral force, of more comprehensive morality than the human being that it creates. Under the symbol of a wise and loving parent—the most just, efficient, and attractive image that we know of—we are encouraged to regard this unseen Authority as being in direct relation with every atom of creation, and as desirous of drawing each atom into progressively higher forms of existence.”

Anarchism: Its Philosophy and Ideal (1896)
Context: Far be it from us not to recognize the importance of the second factor, moral teaching — especially that which is unconsciously transmitted in society and results from the whole of the ideas and comments emitted by each of us on facts and events of every-day life. But this force can only act on society under one condition, that of not being crossed by a mass of contradictory immoral teachings resulting from the practice of institutions.
In that case its influence is nil or baneful. Take Christian morality: what other teaching could have had more hold on minds than that spoken in the name of a crucified God, and could have acted with all its mystical force, all its poetry of martyrdom, its grandeur in forgiving executioners? And yet the institution was more powerful than the religion: soon Christianity — a revolt against imperial Rome — was conquered by that same Rome; it accepted its maxims, customs, and language. The Christian church accepted the Roman law as its own, and as such — allied to the State — it became in history the most furious enemy of all semi-communist institutions, to which Christianity appealed at Its origin.

General sources
Context: Writers are greatly respected. The intelligent public is wonderfully patient with them, continues to read them, and endures disappointment after disappointment, waiting to hear from art what it does not hear from theology, philosophy, social theory, and what it cannot hear from pure science. Out of the struggle at the center has come an immense, painful longing for a broader, more flexible, fuller, more coherent, more comprehensive account of what we human beings are, who we are and what this life is for.

Transhumanism (1957)
Context: We are beginning to realize that even the most fortunate people are living far below capacity, and that most human beings develop not more than a small fraction of their potential mental and spiritual efficiency. The human race, in fact, is surrounded by a large area of unrealized possibilities, a challenge to the spirit of exploration.
