This brutal and pitiless philosophy promises at least frank and close reasoning.

Let us see if it keeps its promise.
"We talk very gravely about the conditions of property,...

as if it was our province to decide what constitutes property....

It would seem, to hear certain philosophers and legislators, that at a certain moment, spontaneously and without cause, people began to use the words THINE and MINE; and that they might have, or ought to have, dispensed with them.
But THINE and MINE were never invented." A philosopher yourself, you are too realistic.

THINE and MINE do not necessarily refer to self, as they do when I say your philosophy, and my equality; for your philosophy is you philosophizing, and my equality is I professing equality.
