“It is reasonable that everyone who asks justice should do justice”

A Vindication of Natural Society (1756)
Context: A good parson once said, that where mystery begins, religion ends. Cannot I say, as truly at least, of human laws, that where mystery begins, justice ends? It is hard to say whether the doctors of law or divinity have made the greater advances in the lucrative business of mystery. The lawyers, as well as the theologians, have erected another reason besides natural reason; and the result has been, another justice besides natural justice. They have so bewildered the world and themselves in unmeaning forms and ceremonies, and so perplexed the plainest matters with metaphysical jargon, that it carries the highest danger to a man out of that profession, to make the least step without their advice and assistance. Thus, by confining to themselves the knowledge of the foundation of all men's lives and properties, they have reduced all mankind into the most abject and servile dependence. We are tenants at the will of these gentlemen for everything; and a metaphysical quibble is to decide whether the greatest villain breathing shall meet his deserts, or escape with impunity, or whether the best man in the society shall not be reduced to the lowest and most despicable condition it affords. In a word, my Lord, the injustice, delay, puerility, false refinement, and affected mystery of the law are such, that many who live under it come to admire and envy the expedition, simplicity, and equality of arbitrary judgments.

I Think I'll Sit This One Out (1939)
Context: Justice alone knows liberty, equality, and fraternity, and justice is a human virtue arising from man's human capacity to reason. We cannot make sense out of justice by looking at the moon or taking dope or building battleships. We can make sense out of justice by using our reason to discover that justice, like wisdom, is better than rubies.

1910s, The World Movement (1910)
Context: Each people can do justice to itself only if it does justice to others; but each people can do its part in the world movement for all only if it first does its duty within its own household. The good citizen must be a good citizen of his own country first before he can with advantage be a citizen of the world at large.

The Economic Tendency of Freethought (1890)
Context: First, then, God, being all-just, wishes to do justice; being all-wise, knows what justice is; being all-powerful, can do justice. Why then injustice? Either your God can do justice and won't or doesn't know what justice is, or he cannot do it. The immediate reply is: "What appears to be injustice in our eyes, in the sight of omniscience may be justice. God's ways are not our ways."
Oh, but if he is the all-wise pattern, they should be; what is good enough for God ought to be good enough for man; but what is too mean for man won't do in a God.
