“The philosopher considering the Universe in its entirety is led to admit that there is only one necessary, absolute being, God. All other beings are contingent; this is why Pascal said of himself: "I feel that I might not have been… therefore I am not a necessary being" (Pensées, No. 597). The proposition applies equally to every living thing.”

Guide for the Perplexed (c. 1190), Part I
Context: Know that this Universe, in its entirety, is nothing else but one individual being; that is to say, the outermost heavenly sphere, together with all included therein, is as regards individuality beyond all question a single being like Said and Omar. The variety of its substances—I mean the substances of that sphere and all its component parts—is like the variety of the substances of a human being: just as, e. g., Said is one individual, consisting of various solid substances, such as flesh, bones, sinews of various humours, and of various spiritual elements; in like manner this sphere in its totality is composed of the celestial orbs, the four elements and their combinations; there is no vacuum whatever therein, but the whole space is filled up with matter. Its centre is occupied by the earth, earth is surrounded by water, air encompasses the water, fire envelopes the air, and this again is enveloped by the fifth substance (quintessence). These substances form numerous spheres, one being enclosed within another so that no intermediate empty space, no vacuum, is left. One sphere surrounds and closely joins the other. All the spheres revolve with constant uniformity, without acceleration or retardation; that is to say, each sphere retains its individual nature as regards its velocity and the peculiarity of its motion; it does not move at one time quicker, at another slower. Compared with each other, however, some of the spheres move with less, others with greater velocity. The outermost, all-encompassing sphere, revolves with the greatest speed; it completes its revolution in one day, and causes every thing to participate in its motion, just as every particle of a thing moves when the entire body is in motion; for all existing beings stand in the same relation to that sphere as a part of a thing stands to the whole. These spheres have not a common centre; the centres of some of them are identical with the centre of the Universe, while those of the rest are different from it. Some of the spheres have a motion independent of that of the whole Universe, constantly revolving from East to West, while other spheres move from West to East. The stars contained in those spheres are part of their respective orbits; they are fixed in them, and have no motion of their own, but participating in the motion of the sphere of which they are a part, they themselves appear to move. The entire substance of this revolving fifth element is unlike the substance of those bodies which consist of the other four elements, and are enclosed by the fifth element.<!--pp.288-292 (1881) Tr. Friedlander

"Angel Surrounded by Paysans" (1949)
Context: I am one of you and being one of you
Is being and knowing what I am and know.
Yet I am the necessary angel of earth,
Since, in my sight, you see the earth again,
Cleared of its stiff and stubborn, man-locked set
And, in my hearing, you hear its tragic drone
Rise liquidly in liquid lingerings,
Like watery words awash; like meanings said
By repetitions of half-meanings. Am I not,
Myself, only half a figure of a sort,
A figure half seen, or seen for a moment, a man
Of the mind, an apparition appareled in
Apparels of such lightest look that a turn
Of my shoulders and quickly, too quickly, I am gone?

Context: I wish to be useful, and every kind of service necessary to the public good becomes honorable by being necessary. If the exigencies of my country demand a peculiar service, its claim to perform that service are imperious.

Context: I believe that the Universe is one being, all its parts are different expressions of the same energy, and they are all in communication with each other, therefore parts of one organic whole. (This is physics, I believe, as well as religion.) The parts change and pass, or die, people and races and rocks and stars, none of them seems to me important in itself, but only the whole. This whole is in all its parts so beautiful, and is felt by me to be so intensely in earnest, that I am compelled to love it and to think of it as divine. It seems to me that this whole alone is worthy of the deeper sort of love and there is peace, freedom, I might say a kind of salvation, in turning one's affections outward toward this one God, rather than inwards on one's self, or on humanity, or on human imaginations and abstractions — the world of spirits.
I think it is our privilege and felicity to love God for his beauty, without claiming or expecting love from him. We are not important to him, but he to us.

Variant translations:
A natural society, in the midst of which every man is born and outside of which he could never become a rational and free being, becomes humanized only in the measure that all men comprising it become, individually and collectively, free to an ever greater extent.
Note 1. To be personally free means for every man living in a social milieu not to surrender his thought or will to any authority but his own reason and his own understanding of justice; in a word, not to recognize any other truth but the one which he himself has arrived at, and not to submit to any other law but the one accepted by his own conscience. Such is the indispensable condition for the observance of human dignity, the incontestable right of man, the sign of his humanity.
To be free collectively means to live among free people and to be free by virtue of their freedom. As we have already pointed out, man cannot become a rational being, possessing a rational will, (and consequently he could not achieve individual freedom) apart from society and without its aid. Thus the freedom of everyone is the result of universal solidarity. But if we recognize this solidarity as the basis and condition of every individual freedom, it becomes evident that a man living among slaves, even in the capacity of their master, will necessarily become the slave of that state of slavery, and that only by emancipating himself from such slavery will he become free himself.
Thus, too, the freedom of all is essential to my freedom. And it follows that it would be fallacious to maintain that the freedom of all constitutes a limit for and a limitation upon my freedom, for that would be tantamount to the denial of such freedom. On the contrary, universal freedom represents the necessary affirmation and boundless expansion of individual freedom.
This passage was translated as Part III : The System of Anarchism , Ch. 13: Summation, Section VI, in The Political Philosophy of Bakunin : Scientific Anarchism (1953), compiled and edited by G. P. Maximoff
Man does not become man, nor does he achieve awareness or realization of his humanity, other than in society and in the collective movement of the whole society; he only shakes off the yoke of internal nature through collective or social labor... and without his material emancipation there can be no intellectual or moral emancipation for anyone... man in isolation can have no awareness of his liberty. Being free for man means being acknowledged, considered and treated as such by another man, and by all the men around him. Liberty is therefore a feature not of isolation but of interaction, not of exclusion but rather of connection... I myself am human and free only to the extent that I acknowledge the humanity and liberty of all my fellows... I am properly free when all the men and women about me are equally free. Far from being a limitation or a denial of my liberty, the liberty of another is its necessary condition and confirmation.
Man, Society, and Freedom (1871)
Context: The materialistic, realistic, and collectivist conception of freedom, as opposed to the idealistic, is this: Man becomes conscious of himself and his humanity only in society and only by the collective action of the whole society. He frees himself from the yoke of external nature only by collective and social labor, which alone can transform the earth into an abode favorable to the development of humanity. Without such material emancipation the intellectual and moral emancipation of the individual is impossible. He can emancipate himself from the yoke of his own nature, i. e. subordinate his instincts and the movements of his body to the conscious direction of his mind, the development of which is fostered only by education and training. But education and training are preeminently and exclusively social … hence the isolated individual cannot possibly become conscious of his freedom.
To be free … means to be acknowledged and treated as such by all his fellowmen. The liberty of every individual is only the reflection of his own humanity, or his human right through the conscience of all free men, his brothers and his equals.
I can feel free only in the presence of and in relationship with other men. In the presence of an inferior species of animal I am neither free nor a man, because this animal is incapable of conceiving and consequently recognizing my humanity. I am not myself free or human until or unless I recognize the freedom and humanity of all my fellowmen.
Only in respecting their human character do I respect my own....
I am truly free only when all human beings, men and women, are equally free. The freedom of other men, far from negating or limiting my freedom, is, on the contrary, its necessary premise and confirmation.
