We need not be surprized, that this should happen in natural philosophy.

The essence and composition of external bodies are so obscure, that we must necessarily, in our reasonings, or rather conjectures concerning them, involve ourselves in contradictions and absurdities.

But as the perceptions of the mind are perfectly known, and I have used all imaginable caution in forming conclusions concerning them, I have always hoped to keep clear of those contradictions, which have attended every other system.

Accordingly the difficulty, which I have at present in my eye, is nowise contrary to my system; but only departs a little from that simplicity, which has been hitherto its principal force and beauty.
The passions of love and hatred are always followed by, or rather conjoined with benevolence and anger.

It is this conjunction, which chiefly distinguishes these affections from pride and humility.
