For envy is an uneasiness; so are emulation, detraction, anguish, sorrow, sadness, tribulation, lamentation, vexation, grief, trouble, affliction, and despair.

The Stoics define all these different feelings; and all those words which I have mentioned belong to different things, and do not, as they seem, express the same ideas; but they are to a certain extent distinct, as I shall make appear perhaps in another place.

These are those fibres of the roots which, as I said at first, must be traced back and cut off and destroyed, so that not one shall remain.

You say it is a great and difficult undertaking: who denies it?
But what is there of any excellency which has not its difficulty?
Yet philosophy undertakes to effect it, provided we admit its superintendence.

But enough of this.
The other books, whenever you please, shall be ready for you here or anywhere else.
