World Philosophy Day 2026: 5 ready-to-use classroom activities

UNESCO celebrates World Philosophy Day on the third Thursday of November. In 2026 it falls on Thursday, November 19.

It is a good excuse to take philosophy out of the list of names and dates and bring it to what really worries students: exams, social media, friendships, the fear of making mistakes. These five activities come from the exercises in Talks on a Park Bench, written by María Ferrer Tarazona, a high school philosophy teacher. You can use them separately, in a 50-minute session, or chain them together throughout the week.

1. The two-column list (Epictetus)

Duration: 15 minutes · Level: from the 3rd year of ESO (Spain's compulsory secondary education, ages 14–15)

Idea: the dichotomy of control. There are things that depend on us (our judgments, our decisions) and things that don't (other people's opinions, the result of an exam already handed in).

How it works:

1. Each student chooses something that worries them right now, without needing to share it.
2. They divide a sheet of paper into two columns: "up to me" and "not up to me".
3. They fill in both about that specific worry.
4. Voluntary sharing: has anyone discovered something placed in the wrong column?

For debate: does "not up to me" mean "doesn't matter"? It is the most common mistake with this idea and the best starting point for discussing it. We explain it in Epictetus' dichotomy of control.

2. The silent count (Seneca)

Duration: one day (outside class) and 15 minutes of sharing · Level: from the 3rd year of ESO

Idea: Seneca wrote in On the Shortness of Life that life is not short, but that we waste it spread across a thousand directions we don't choose.

How it works: for one day, every time the student unlocks their phone without a specific reason, they make a mark on a piece of paper they carry in their pocket. No judging themselves, just counting. The next day, the numbers are compared anonymously.

For debate: are we less disciplined than previous generations, or are we facing apps designed specifically to capture our attention? What would Seneca say about notifications?

3. The day without metrics (diligence versus toxic productivity)

Duration: weekend task and 15 minutes of sharing · Level: 4th year of ESO (ages 15–16) and Bachillerato (ages 16–18)

Idea: it is not the same to strive because something matters to you as to strive so that a number tells you that you are worth something.

How it works: each student chooses an activity they like (an instrument, a sport, drawing, writing) and does it for a day without measuring anything: no stopwatch, no step counter, without posting it afterward. Then they answer: did the feeling change? How would you feel if no one else knew you had done it?

For debate: the difference between diligence and toxic productivity, and why Aristotle considered leisure, the scholē that the word "school" comes from, the highest activity of the human being.

4. The map of circles (Hierocles)

Duration: 25 minutes · Level: from the 4th year of ESO

Idea: the Stoic Hierocles imagined each person surrounded by concentric circles: oneself, family, friends, community, country and humanity. The ethical task is to draw the distant circles closer to the center.

How it works: each student draws their circles and places people from their life in them (using initials). Then they answer: in which circle do I invest the most real time? Does it match the one that matters most to me?

You can find the full development of this activity, with debate questions, in Hierocles' circles.

5. One "I don't know" a week (the Skeptics)

Duration: 10 minutes of introduction and one week of practice · Level: Bachillerato

Idea: the ancient Skeptics practiced suspension of judgment on the great questions without a clear answer. Needing to win every argument and always having a firm opinion on everything produces a wear and tear that they had already identified.

How it works: the challenge is to say out loud, at least once during the week, a sincere "I don't know" or "I'm not sure" in response to a question you truly don't have clear, instead of improvising an opinion.

For debate: the limit of the idea. Not all questions deserve the same doubt: using skepticism to deny well-established facts or to avoid committing to anything would be a distortion, not an honest application.

A tip to make them work

These activities work best when they don't feel like a lesson but a conversation. That is why Talks on a Park Bench begins each chapter with a scene among four friends, Marc, Nora, Diego and Vera, in which the problem appears before the philosopher. Reading one of those scenes aloud before each activity is usually enough to open the debate.

The book brings together more than twenty philosophers, from Epictetus and Hypatia to Simone Weil and Hannah Arendt, and each chapter ends with practical exercises designed to take into the classroom or do alone.
