expressions like _until the time when_, _during the time when_, &c. Hence,
in an expression like _seek out his wickedness till thou_ find (not
_findest_) _none_, the principle of the construction is nearly the same as
in _he that troubled you_, &c., or _vice vers[^a]_.[64]

s. 508. In most conditional expressions the subjunctive mood should follow
the conjunction. All the following expressions are conditional.

1. _Except_ I _be_ by Silvia in the night,
There is no music in the nightingale.--SHAKSPEARE.

2. Let us go and sacrifice to the Lord our God, _lest_ he _fall_ upon
us with pestilence.--_Old Testament._

3. ----Revenge back on itself recoils.
Let it. I reck not, _so_ it _light_ well aimed.--J. MILTON.

4. _If_ this _be_ the case.

5. _Although_ my house _be_ not so with God.--_Old Testament._

6. He shall not eat of the holy thing _unless_ he _wash_ his flesh with
water.--_Old Testament._

Expressions like _except_ and _unless_ are equally conditional with words
like _if_ and _provided that_, since they are equivalent to _if--not_.

Expressions like _though_ and _although_ are peculiar. They join
propositions, of which the one is a _prim[^a] facie_ reason against the
existence of the other: and this is the conditional element. In the
sentence, _if the children be so badly brought-up, they are not to be
trusted_, the _bad bringing-up_ is the reason for their being _unfit to be
trusted_; and, as far as the expression is concerned, _is admitted to be
so_. The only uncertainty lies in the question as to the degree of the
badness of the education. The inference from it is unequivocal.

But if, instead of saying _if_, we say _although_, and omit the word _not_,
so that the sentence run _although the children be so badly brought-up they
are to be trusted_, we do two things: we indicate the general relation of
cause and effect that exists between _bad bringing-up_ and _unfitness for
being trusted_, but we also, at the same time, take an exception to it in
the particular instance before us. These remarks have been made for the
sake of showing the extent to which words like _though_, &c., are
conditional.

It must be remembered, however, that conjunctions, like the ones lately
quoted, do not govern subjunctive moods because they are conditional, but
because, in the particular condition which they accompany, there is an
element of uncertainty.
