CHAP. II.
The conditions requisite to Secrecy,
The use of it in the Matter of speech,
either
By
Fables of the Heathen.
Parables of Scripture.
TO the exactnesse of Secrecy in
any way of discourse, there
are these two qualifications requi∣site.
1. That it be difficult to be un∣folded,
if it should bee doubted of,
or examined.
2. That it be (if possible) altoge∣ther
devoid of suspicion; for so far
as it is liable to this, it may be said to
come short in the very Nature of
Secrecy; since what is once suspe∣cted,
is exposed to the danger of exa∣mination,
& in a ready way to be dis∣covered:
but if not, yet a man is
more likely to be disappointed in his
descriptionPage 14
intention, when his proceedings are
mistrusted.
Both these conditions together are
to bee found but in few of the fol∣lowing
instances; only they are here
specified, to shew what a man should
aime at, in the inventions of this na∣ture.
The art of secret information in
the generall, as it includes all signifi∣catory
signes, may be stiled Cryptome∣nysis,
or private Intimations.
The particular wayes of discour∣sing,
were before intimated to bee
threefold.
1. By Speaking.
2. By Writing.
3. By signes or gestures.
According to which variety, there
are also different wayes of Secrecy.
1. Cryptologia.
2. Cryptographia.
3. Semaeologia.
Cryptologia, or the Secrecy of spea∣king,
may consist either,
descriptionPage 15
1. In the matter.
2. In the words.
1. In the Matter: when the thing
we would utter is so concealed under
the expression of some other matter,
that it is not of obvious conceit. To
which purpose are the Metaphors,
Allegories, and divers other Tropes
of Oratory: which, so farre as they
concerne the ornament of speech, d••••
properly belong to Rhetorick, but as
they may be applied for the secrecy
of speech, so are they reducible unto
this part of Grammar.
To this likewise appertaines all
that aenigmaticall learning, unto which
not onely the learned heathen, but
their Gods also were so much devo∣ted,
as appeares by the strange and
frequent ambiguities of the Oracles,
and Sybils. And those were counted
the most profound Philosophers a∣mongst
them, who were best able for
the invention of such affected ob∣scurities.
Of this kind also were all those
descriptionPage 16
mysterious Fables, under which, the
ancients did veile the secrets of their
Religion and Philosophy; counting it a
prophane thing to prostitute the hid∣den
matters of either, unto vulgar ap∣prehension.
Quia sciunt inimicam esse
naturae, apertam nudamque expositionem
sui; quae, sicut vulgaribus hominum sen∣sibus,
intellectum sui, vario rerum teg∣mine
operimentoque subtraxit, ita a prui dentibus
arcana sua voluit per fabulosa
tractari, saith Macrobius. The Gods
and nature wold not themselves have
hidden so many things from us, if
they had intended them for com∣mon
understandings, or that others
should treat of them, after an easie &
perspicuous way: Hence was it that
the learned men of former times were
so generally inclined, to involve all
their learning, in obscure & mysteri∣ous
expressions. Thus did the Egyptian
Priests, the Pythagoreans, Platonicks, &
almost all other sects and professions.
And to this generall custome of
those ages (we may guesse) the holy-Ghost
descriptionPage 17
do's allude, in the frequent
Parables, both of the old and new
Testament.Parabola est sermo similitu∣dinarius,
qui aliud dicit, aliud signifi∣cat,
saith Aquinas. It is such a speech
of similitude, as sayes one thing, and
meanes another. The Disciples doe
directly oppose it to plaine speaking.
Behold now speakest thou plainly,and no
Parables.
And elsewhere tis intimated, that
our Saviour did use that manner of
teaching for the Secrecy of it: That
those proud and perverse auditors,
who would not applie themselves to
the obedience of his doctrine, might
not so much as underst and it. To
whom it is not given to know the myste∣ries
of the Kingdome of God,to them all
things are done in Parables,that seeing
they may see and not perceive, and hea∣ring
they may heare and not understand.
The art of these was so to implie a
secret argument, that the adversary
might unawares be brought over, to
an acknowledgement, and confession
descriptionPage 18
of the thing we would have. Thus did
Nathan, unexpectedly discover to
David, the cruelty and injustice of
his proceedings in the case of Vriah.
Thus did another Prophet, make A∣hab,
condemne himselfe, for suffering
the King of Syria to escape. And by
this meanes did our Saviour in the
Parable of the Vineyard, and the un∣just
husband-man, force the unbelee∣ving
Jewes, to a secret acknowledge∣ment,
of those judgements, they had
themselves deserved.
Of this nature was that argument
of an antient Orator, who when the
enemies had proposed peace, upon
this condition, that the City should
banish their teachers and Philoso∣phers;
He steps up and tells the peo∣ple
a tale, of certaine warres betwixt
the woolves and the sheepe, and that
the woolves promised to make a
league, if the sheep would put away
their mastiffe Dogs. By this meanes
better instructing them of the dan∣ger
and madnesse there would be in
descriptionPage 19
yeelding to such a condition.
The Jewish Doctors doe general∣ly
in their Talmud, and all their
others writings, accustome them∣selves
to a Parabolicall way of tea∣ching;
and 'tis observed that many
of those horrid fables, that are fa∣thered
upon them, doe arise from a
misapprehension of them in this par∣ticular.
Whilst others interpret
that according to the letter, which
they intended onely for the morall.
As that which one Rabby relates
concerning a Lion in the forrest of
Elay, that at the distance of foure
hundred leagues, did with his roa∣ring,
shake downe the walls of Rome,
and make the women abortive.
Wherein he did not affirme the exi∣stence
of any such monster, but only
intimate the terriblenesse and power
of the divine Majestie. But this by
the way.
By this Art, many men are able
in their ordinary discourses, so se∣cretly
to convey their counsels, or
descriptionPage 20
reproofes, that none shall under∣stand
them, but those whom they
concerne. And this way of teaching
hath a great advantage above any
other, by reason it hath much more
power in exciting the fancy and af∣fections.
Plaine arguments, and
morall precepts barely proposed,
are more flat in their operation,
not so lively and perswasive, as when
they steale into a mans assent, under
the covert of a parable.
To be expert in this particular is
not in every mans power; like Poe∣trie,
it requires such a naturall fa∣cultie
as cannot be taught. But so
farre as it falls under the rules and
directions of Art, it belongs to the
precepts of Oratory.
In the generall 'tis to be observed,
that in these cases a man must be ve∣ry
carefull to make choyse of such a
subject, as may beare in it, some pro∣per
analogie and resemblance to the
chiefe businesse. And he must before∣hand
in his thoughts, so aptly con∣trive
descriptionPage 21
the severall parts of the simili∣tude,
that they may fitly answere un∣to
those particular, passages, which
are of greatest consequence.
