Kitap 2
19.17
In the first place, if that which is naturally less likely has happened, then that which is more likely will most probably have happened. If that which usually happens afterwards has happened, then that which precedes must also have happened; for instance, if a man has forgotten a thing, he must once have learnt it.
19.18
If a man was able and wished to do a thing, he has done it; for all men do a thing, when they are able and resolve to do it, for nothing hinders them.
19.19
Further, if a man wished to do it and there was no external obstacle; if he was able to do it and was in a state of anger; if he was able and desired to do it; for men as a rule, whenever they can, do those things which they long for, the vicious owing to want of self-control, the virtuous because they desire what is good.
19.20
And if anything was on the point of being done, it most probably was done; for it is likely that one who was on the point of doing something has carried it out.
19.21
And if all the natural antecedents or causes of a thing have happened; for instance, if it has lightened, it has also thundered; and if a man has already attempted a crime, he has also committed it. And if all the natural consequences or motives of actions have happened, then the antecedent or the cause has happened; for instance, if it has thundered, it has also lightened, and if a man has committed a crime, he has also attempted it.
