“It is a bitter thing that each of us must finally be blown out like a candle, and have the unique ardor of his individual flame choked off, and sucked utterly away like smoke in the dark. Do we ever accept this in our hearts, any of us? The waste of knowledge! It never ceases to be…infuriating.”

Book I, 1.144-[3]
Variant translation: We must realize, too, that, both for cities and for individuals, it is from the greatest dangers that the greatest glory is to be won.

Part I : Declaration, Ch. IV : Mr. Spencer's Confusion as to Rights
A Perplexed Philosopher (1892)
Context: Men must have rights before they can have equal rights. Each man has a right to use the world because he is here and wants to use the world. The equality of this right is merely a limitation arising from the presence of others with like rights. Society, in other words, does not grant, and cannot equitably withhold from any individual, the right to the use of land. That right exists before society and independently of society, belonging at birth to each individual, and ceasing only with his death. Society itself has no original right to the use of land. What right it has with regard to the use of land is simply that which is derived from and is necessary to the determination of the rights of the individuals who compose it. That is to say, the function of society with regard to the use of land only begins where individual rights clash, and is to secure equality between these clashing rights of individuals.

The Nuts of Knowledge (1903)
Context: We must pass like smoke or live within the spirit's fire;
For we can no more than smoke unto the flame return
If our thought has changed to dream, our will unto desire,
As smoke we vanish though the fire may burn.
