Lesson 02 · 7 min
Three species
Forensic, deliberative, and epideictic speech, sorted by the judgment the audience is asked to make.

Name the judgment first
Aristotle sorted civic speech by the judgment the audience is asked to make. Time is a clue to that job, not the test. A tribute can spend its length on the past and still be praise. Learn the division as a diagnostic, not as a costume.
Forensic
Judging past conduct. What happened, who did it, and whether it was just. Courts, incident reviews, the post that reconstructs a breakdown. Also called judicial. The past is the usual clue.
Deliberative
Choosing a future action. What we should do, given costs and chances. Policy, roadmaps, advice, any real proposal. Also called legislative or advisory.
Epideictic
Affirming what deserves praise or blame. The speech displays what a community honors now. It may recall the past or look ahead. Toasts, eulogies, manifestos, commencement talks. Also called ceremonial.
Forensic
Judge past conduct
Usually the past
Deliberative
Choose an action
Usually the future
Epideictic
Affirm a value
Any tense
One of them is in charge
A recall notice reconstructs the past, recommends a next step, and tries to show that the company still deserves trust. Name the species doing the main job. The others are supporting it.
Misread the species and you will answer the wrong assignment. A jury does not need a vision statement. A toast is a poor place to smuggle a budget, unless the budget is the value you are actually praising, in which case say so.
Kairos
Kairos is the fit between an argument and its moment. The same claim can be exact and still be clumsy, because the audience cannot hear it yet, or cannot hear it anymore.
Species: Aristotle, Rhetoric I.3. The division starts with the audience's job. Kairos is older than that treatise. It is the Greek sense of the opportune moment, not a fourth species. Rhetoric I.3
Try it
Sort the job
Practice, not a completion check. Tap the species that is in charge. Ignore the costume.
Here is what the checkout did between 2:11 and 2:40.
We should cut the add-on, not the core plan.
This is what a careful team looks like when nobody is watching.
Checks
Completion check. Choose the distinction the lesson is drawing. A wrong guess stays visible long enough to read, then you can try again. The lesson is recorded when each check is in place. The Try it above, when there is one, is practice and does not record the lesson.
