I am content to treat this type of argument as a genus without going further; others however divide it into species. For we may argue from several things to one or from one thing to several; hence arguments such as What has happened once may happen often. We may also argue from a part to a whole, from genus to species, from that which contains to that which is contained, from the difficult to the easy, from the remote to the near, and similarly from the opposites of all these to their opposites.

Now all these arguments deal with the greater or the less or else with things that are equal, and if we follow up such fine distinctions, there will be no limit to our division into species. For the comparison of things is infinite; things may be more pleasant, more serious, more necessary, more honourable, more useful. I say no more for fear of falling into that very garrulity which I deprecate.
