“It is, civilly, all aptitudes having equal opportunity; politically, all votes having equal weight; religiously, all consciences having equal rights.”

The Life Process is the End—not man, nor any other animal temporarily privileged to weave a world's philosophy. Non-human beings were not made for human beings any more than human beings were made for non-human beings. Just as the sidereal spheres were once supposed by the childish mind of man to be unsubstantial satellites of the earth, but are known by man's riper understanding to be worlds with missions and materialities of their own, and of such magnitude and number as to render terrestrial insignificance frightful, so the billions that dwell in the seas, fields, and atmospheres of the earth were in like manner imagined by the illiterate children of the race to be the mere trinkets of men, but are now known by all who can interpret the new revelation to be beings with substantially the same origin, the same natures, structures, and occupations, and the same general rights to life and happiness, as we ourselves.

Context: The word “equality” is often used, but, wisely, rarely defined. The moment one tries to define it, one gets into great difficulty. For example, it cannot mean equality of incomes or earnings; otherwise, we would not need more than one union. Indeed, we would not need one union. If we are to have opportunity, we cannot have equality, because the two are opposite. We may have equality of opportunity, but if the only opportunity is to be equal, it is not opportunity.

Science in a Free Society (1978)
Context: A free society is a society in which all traditions have equal rights and equal access to the centers of power. A tradition receives these rights not because the importance the cash value, as it were) it has for outsiders but because it gives meaning to the lives of those who participate in it.

Context: It is my interpretation from the Koran that all people have equal rights. That means men and women, Muslims and non-Muslims too, and in a society where all people have equal rights, that means all people should make decisions equally. … This doesn't mean that we're changing God's law, It just means we're reinterpreting laws according to the development of science — and the realities of the times.

1910s, The New Nationalism (1910)
Context: Practical equality of opportunity for all citizens, when we achieve it, will have two great results. First, every man will have a fair chance to make of himself all that in him lies; to reach the highest point to which his capacities, unassisted by special privilege of his own and unhampered by the special privilege of others, can carry him, and to get for himself and his family substantially what he has earned. Second, equality of opportunity means that the commonwealth will get from every citizen the highest service of which he is capable. No man who carries the burden of the special privileges of another can give to the commonwealth that service to which it is fairly entitled.

Those are undeniable truths.

Context: Those who are most to be considered, those for whose help the struggle must be made, if labor is to be enfranchised, and social justice won, are those least able to help or struggle for themselves, those who have no advantage of property or skill or intelligence, — the men and women who are at the very bottom of the social scale. In securing the equal rights of these we shall secure the equal rights of all.
Hence it is, as Mazzini said, that it is around the standard of duty rather than around the standard of self-interest that men must rally to win the rights of man. And herein may we see the deep philosophy of Him who bade men love their neighbors as themselves.
In that spirit, and in no other, is the power to solve social problems and carry civilization onward.
