Tract VI: On the Virtue of Truth

Usefulness. - It is necessary that in this tract we learn to esteem greatly the noble virtue of truth and sincerity; to discern well and preserve the various offices of secrecy; and finally so to protect secrecy itself that we may continue to detest and flee lying according to its true notion.

Order of speaking. The order of speaking, intimated by the very usefulness proposed, will be this: that in three successive chapters we treat of veracity, of secrecy, and of lying.
