The last page said what this art is for. The application will make you do it. Open Ars Syllogistica and complete the opening study, What Is Logic · An Orientation — the unscored deck the app itself marks “start here.” Then enter the First Act of the Mind · Simple Apprehension. Four exercises are open from the start: the Predicables, the Categories, Division, and Definition. Work them; do not skip to the syllogism because it looks like “real logic.” The first two acts are why the third can be an act at all. Division and Definition are the gate to the Second Act (the proposition). The Third Act (reasoning) waits until the second is passed.
If you have had little grammar, the app also offers a preliminary card, The Art of Grammar. This course has already sent you through grammar; use that card only if the terms will not stay still. Enable tracking on the Progress page if you want the Guided Path to remember you. Nothing is stored until you do, and nothing leaves this browser.
Return to this course when you can say, in your own words, what follows from what, and what only appears to. A good test is Conway’s accent on appears: if you can catch a paragraph that walks like an argument and does not conclude, you have the question this lesson needed. The app will then take you into opposition, immediate inference, and the syllogism. This walk-through will not duplicate those drills.
Begin at What Is Logic · An Orientation, which the app marks “start here,” then the First Act. Live address: syllogistica.studiuminstitute.org.
Open Ars Syllogistica practice
Default recommendation: finish a first pass of the First Act before hunting syllogisms. Return to grammar when names will not stay still. Look ahead at rhetoric only when you notice yourself treating argument as a contest to be won rather than a discourse to be ordered — and even then, come back. The cycle is the same as at grammar: doctrine, then practice, then doctrine again with better questions.
When you come back
Again, you decide when the first pass is done. The test is not the number of exercises passed but whether these will come, unprompted:
- The three acts, in order, and what each produces — a definition, a statement, an argument.
- Why a single term is neither true nor false, and what has to happen before anything can be.
- The difference between a contradiction and a disagreement.
- Conway’s accent on appears: what an expert fallacy looks like, as against an amateur one.
If you can catch a paragraph that walks like an argument and does not conclude — one that was not labelled for you — you have what this lesson was for.
Welcome back
Two arts have now been practised and not merely read. Notice what has changed in the first one: grammar will look different to you now, because you have seen what logic needs from it. That is the ordinary shape of a liberal art — the earlier art is understood better from the later.
Go on to Rhetoric. The third art begins from a failure the first two cannot repair: a thing well said and truly shown, and a hearer who has not seen it.
Come back to logic whenever something has the gait of an argument and you cannot say whether anything followed. And if, in the middle of an inference, you cannot tell what is being said of what, the trouble is behind you, in grammar — go there first.
