exordium is prior in order to the narrative.
Besides these senses of the word, there is a fourth. That which is
better and more honourable is said to have a natural priority. In
common parlance men speak of those whom they honour and love as
'coming first' with them. This sense of the word is perhaps the most
Such, then, are the different senses in which the term 'prior' is
Yet it would seem that besides those mentioned there is yet another.
For in those things, the being of each of which implies that of the
other, that which is in any way the cause may reasonably be said to be
by nature 'prior' to the effect. It is plain that there are
instances of this. The fact of the being of a man carries with it
the truth of the proposition that he is, and the implication is
reciprocal: for if a man is, the proposition wherein we allege that he
is true, and conversely, if the proposition wherein we allege that
he is true, then he is. The true proposition, however, is in no way
the cause of the being of the man, but the fact of the man's being
does seem somehow to be the cause of the truth of the proposition, for
the truth or falsity of the proposition depends on the fact of the
man's being or not being.
Thus the word 'prior' may be used in five senses.
The term 'simultaneous' is primarily and most appropriately
applied to those things the genesis of the one of which is
simultaneous with that of the other; for in such cases neither is
prior or posterior to the other. Such things are said to be
simultaneous in point of time. Those things, again, are 'simultaneous'
