that inwardly lusteth or desires, although he
follow not those desires by a consequent act, Because such motions are not
pure passions, but involve negations of due acts which ought to have been
in lieu thereof: A man may be incestuous [30]that never bodily commits the
act; and from these impure fires, which men kindle and cherish within them,
they are usually in love with their deformed lusts, as _Alcaeus_ was with
the warts [31]in his Boys face, though they are deformed marks. When
_Brutus_ and _Cassius_ assaulted _Caesar_ with a design and resolution to
murther him, we read, that as soon as he saw _Brutus_ he cryed {25} out,
[Greek: Kai su teknon]; _And art thou here my Son, my Darling_? and opened
his breast to him. So when any Lust comes to assault us with a design to
make us dead in sin, we court and caress it in _Caesars_ words, Art thou
here, my Darling? and open our hearts and breasts unto it; whereas we
should alwayes be prepared with preservatories against it.

4. Let your discourse be alwayes chast and pure: Decline with great care
all undecent obscenity in your language, chastening and confining your
tongue, and restraining it with Grace; for, as St. _James_ tells us, _Jam_.
3. 2. _If any man offend not in word_ (tongue) _the same is a perfect man,
and able also to bridle the whole body._ Either be silent, or speak those
things which are better then silence, is a good Rule here. Every bad tree
is known by its bad fruit, and an unclean man may be trac'd by his unclean
discourse; it being a shrewd symptom the Will is depraved, when our
Discourse is unchaste and obscene. And in this [32]_Hierocles_ concurrs
with me; _The Will of man_ {26} (saith he) _adhering long neither to Virtue
nor Vice, utters forth expressions inclining to both, as resembling the
contrary affections in it_. This advice therefore of _Tyrius Maximus_ is
very soveraign; [33]_I require such a pleasure in words which Virtue may
not disdain to make her Waiting-woman and attend upon her._ St. _James_
calls the Tongue a _fire_, Jam. 3. 6. And the School-men call the Lusts of
the Flesh (_Fomes_) Tinder. Let us therefore be careful that the Fire of
our Tongue light not upon this Tinder, and kindle it. Modesty and a
becoming Blush is the _Fence_ of all Virtue; and when this is broken down
by obscene talk, the _Banks_ will overflow with impure _Streams_. A Rose,
when it hath lost its blush, and begins to look pale, by those symptoms you
may conclude t
