“You cannot have a proud and chivalrous spirit if your conduct is mean and paltry; for whatever a man's actions are, such must be his spirit.”

What Is Anarchism? (1929), Ch. 26: "Preparation" http://libcom.org/library/what-is-anarchism-alexander-berkman-26
Context: If your object is to secure liberty, you must learn to do without authority and compulsion. If you intend to live in peace and harmony with your fellow-men, you and they should cultivate brotherhood and respect for each other. If you want to work together with them for your mutual benefit, you must practice cooperation. The social revolution means much more than the reorganization of conditions only: it means the establishment of new human values and social relationships, a changed attitude of man to man, as of one free and independent to his equal; it means a different spirit in individual and collective life, and that spirit cannot be born overnight. It is a spirit to be cultivated, to be nurtured and reared, as the most delicate flower it is, for indeed it is the flower of a new and beautiful existence.

Context: This freedom of communication is indispensable for the development and extension of scientific knowledge, a consideration of much practical import. In the first instance it must be guaranteed by law. But laws alone cannot secure freedom of expression; in order that every man may present his views without penalty there must be a spirit of tolerance in the entire population. Such an ideal of external liberty can never be fully attained but must be sought unremittingly if scientific thought, and philosophical and creative thinking in general, are to be advanced as far as possible.

The Spirit of Love (1752) http://www.ccel.org/ccel/law/love/files/love1.htm.
Context: Now the Spirit of Love has this Original. God, as considered in himself in his Holy Being, before any thing is brought forth by him or out of him, is only an eternal Will to all Goodness. This is the one eternal immutable God, that from Eternity to Eternity changeth not, that can be neither more nor less nor any thing else but an eternal Will to all the Goodness that is in himself, and can come from him. The Creation of ever so many Worlds or Systems of Creatures adds nothing to, nor takes any thing from this immutable God. He always was and always will be the same immutable Will to all Goodness. So that as certainly as he is the Creator, so certainly is he the Blesser of every created Thing, and can give nothing but Blessing, Goodness, and Happiness from himself because he has in himself nothing else to give. It is much more possible for the Sun to give forth Darkness, than for God to do, or be, or give forth anything but Blessing and Goodness. Now this is the Ground and Original of the Spirit of Love in the Creature; it is and must be a Will to all Goodness, and you have not the Spirit of Love till you have this Will to all Goodness at all Times and on all Occasions. You may indeed do many Works of Love and delight in them, especially at such Times as they are not inconvenient to you, or contradictory to your State or Temper or Occurrences in Life. But the Spirit of Love is not in you till it is the Spirit of your Life, till you live freely, willingly, and universally according to it. For every Spirit acts with Freedom and Universality according to what it is. It needs no command to live its own Life, or be what it is, no more than you need bid Wrath be wrathful. And therefore when Love is the Spirit of your Life, it will have the Freedom and Universality of a Spirit; it will always live and work in Love, not because of This or That, Here or There, but because the Spirit of Love can only love, wherever it is or goes or whatever is done to it. As the Sparks know no Motion but that of flying upwards, whether it be in the Darkness of the Night or in the Light of the Day, so the Spirit of Love is always in the same Course; it knows no Difference of Time, Place, or Persons, but whether it gives or forgives, bears or forbears, it is equally doing its own delightful Work, equally blessed from itself. For the Spirit of Love, wherever it is, is its own Blessing and Happiness because it is the Truth and Reality of God in the Soul, and therefore is in the same Joy of Life and is the same Good to itself, everywhere and on every Occasion.
