It’s important that the teacher/facilitator always keeps in mind that the whole point of doing philosophy with young people is to help the students develop their own thinking! The role of the teacher/facilitator is guide the discussion without attempting to control its content. In other words, do not plan to dictate the substance of the discussion, but rather provide the tools and structure for the discussion to take place among the participants/students.

Remember it’s a balancing act between helping students achieve philosophical clarity and depth and refraining from imposing on the conversation your own preferences for subject matter. This requires sensitivity, skill and practice; push too hard and you’ll monopolize the conversation, but if you do not provide enough structure the students can end up following tangents at length or simply engaging in an opinion-sharing exercise, and making no progress!

To assist you in getting started, we have compiled a list of things to do and not to do that we have found helpful for new and experienced philosophy educators alike.


Things To Do

Hint: Let the discussion flow from the students’ questions and ideas. After reading a story or doing an activity, ask, “What questions did this make you think of?”

  • Encourage the students to build on each other’s ideas.
  • Show the students that what they say makes you think.
  • Encourage the students to speak to one another.

Things Not To Do

  • Tell the students their answers are right or wrong.
  • Plan to teach the students some philosophical argument or point.
  • Insist on your own views.
  • Be uncomfortable with or try to fill-in intervals of silence.
  • Give a definitive answer to a philosophical question.
  • Permit lengthy discussions of relatively unimportant issues.
  • Monopolize the discussion.
  • Resolve issues for them.
  • Try to show the students how philosophically sophisticated you are.

Good leading questions to ask in a philosophy session:

  • “What did you mean when you said . . .?”
  • “That’s an interesting idea. Can you explain what you were thinking when you said that?”
  • “When you said . . . , did you mean . . . ?”
  • “How does what you just said relate to what ____ said a moment ago?”
  • “So if what you just said is true, is ____ also true?”
  • “When you said ____, were you assuming ____?”

Most classroom philosophy sessions are arenas for discussions about the ideas and questions of philosophy, as opposed to being primarily focused on what historical and contemporary philosophers have to say about these ideas and questions. That is, we engage young people in the practice of philosophy. A powerful model for this educational approach is the community of philosophical inquiry.

Lipman and the Community of Inquiry

Matthew Lipman’s detailed conception of the community of inquiry—in which students and teacher(s) learn from one another— was among his most significant contributions to the field.

The community of inquiry, as Lipman conceived it, includes the following characteristics:

  • The enterprise is based on mutual respect;
  • The students build on one another’s ideas and follow the argument where it leads;
  • Students challenge each other to supply reasons for their opinions;
  • Students assist one another in drawing out inferences from what has been said; and
  • Students endeavor to identify one another’s assumptions.

The members of the community of inquiry come together in a spirit of intellectual freedom to explore the more problematic and puzzling aspects of situations and curriculum concepts, rather than emphasizing the “facts.”

The Community of Philosophical Inquiry

The community of inquiry model can be used to explore any subject matter in the classroom. The special features of a community of philosophical inquiry (CPI) involve the content (i.e., philosophical topics). Philosophical topics examine meanings, attempt to clarify concepts, and generally engage abstract questions whose answers are contestable, rather than final or settled.

In a CPI, the students’ philosophical questions shape the scope of the inquiry. Teachers guide the students in inquiry, but do not control the content of the discussion and often don’t know ahead of time what the topic or topics under consideration will be.

The teacher’s role here is robust, but subtle. Teachers pay close attention to the initiation and progress of the dialogue, look for connections among what students say, ask for clarification and reasons, and are attuned to the philosophical content of questions and ideas that might otherwise be lost. This entails a delicate balance between supporting students’ attainment of philosophical clarity and depth and refraining from imposing the teacher’s own preferences for subject matter and the direction of the discussion.

Central features of a Community of Philosophical Inquiry (CPI)

  • The content is philosophical: Members of a CPI are engaged in a structured, collaborative inquiry aimed at building meaning and acquiring understanding through the examination of philosophical questions or concepts of interest to the participants.

  • Epistemic Modesty: A CPI entails a consensus of ‘epistemological modesty’—an acknowledgement that all members of the group, including the facilitator, are fallible, and therefore hold views that could end up being mistaken. Teachers in a CPI facilitate students’ ability to think for themselves about the fundamental aspects of human existence. We demonstrate a reticence about advocating for our own philosophical views and model a comfort with uncertainty and with the fact that we don’t have final settled answers philosophical questions.

  • Avoiding the use of jargon: Participants in a CPI generally refrain from using much technical philosophical language or referring often to the work of professional philosophers. This helps to ensure that the group focuses on exploring the questions themselves and not the past or current history of the subject among professional philosophers.

  • Intellectual Safety: The CPI is an environment of intellectual safety, one in which any question or comment is acceptable, so long as it does not belittle or devalue others in the group, and which allows trust and a corresponding willingness to present one’s thoughts to participants. The teacher models openness and respect for others’ ideas and constructs a structured space that invites the students to engage thoughtfully and with an appreciation for multiple perspectives

While an intellectually safe learning community involves trust, respect, and an atmosphere conducive to taking intellectual risks, it does not promise comfort. Communities of inquiry are dedicated to the open and rigorous exploration of difficult and contestable issues and the intellectual growth that results, the process of which can often provoke feelings of perplexity and uncertainty. This can be an uncomfortable experience. Feeling intellectually safe, therefore, is not to feel complacent or unchallenged—it is to feel supported in one’s struggles to make sense of the world for ourselves.

One practical tool to begin to fashion an intellectually safe atmosphere is to help the students set the rules for the community of inquiry at the beginning of the year. The rules can be posted so that they are always visible during philosophy sessions, and you can remind the students of them from time to time.

Why do we need to encourage students to think philosophically?
Philosophy helps awaken students’ sensitivities to the complex dimensions of their lived experiences and provides them with the awareness and tools needed to navigate the social, emotional, political and ethical aspects of their lives.


Developing an awareness of the philosophical dimensions of our lives – sometimes characterized by philosopher Jana Mohr Lone as developing “philosophical sensitivity” – is a key outcome of engaging in philosophy at an early age. For example, as children learn to recognize when situations have an ethical dimension, they begin to appreciate that how they respond in such situations will help determine both whether those situations become more or less good, right or just, and the kind of persons they are becoming.
The central method of philosophical inquiry is careful, logical, and rational thinking.


Philosophy has always been preoccupied with good thinking, with logic being one of its oldest branches. While formal logic is beyond the skill of most young children, they are very capable of the informal logical operations that constitute basic reasoning, including:

  • Giving reasons
  • Considering evidence
  • Agreeing and disagreeing
  • Giving examples and counter-examples
  • Making comparisons and distinctions

One of the important objectives of philosophy is to develop students’ critical thinking abilities.



Philosophy helps young people learn how to reason and think well, and to hold respectful and rational conversations with their peers. Philosophy also helps students learn how to have confidence in their own unique ideas.
Philosophical discussions provide students with opportunities to practice important communicative and social skills.


Additionally, young people who participate in disciplined philosophical dialogue can learn to overcome shyness, aggression and attention-grabbing behaviors for the sake of cooperating in a kind of group work they find meaningful.

When engaging in a philosophical discussion, students practice such skills as:

For more about the importance of philosophy for young people, see the page “Why Philosophy?”

How do you philosophize with children?
One of the most ancient, the most effective, and the most widespread methods of philosophical inquiry is dialogue: a conversation centered on a particular question or problem, in which the participants share diverse views about it, clarify each other’s thinking, offer multiple possible answers, and test those answers by coming up with reasons for and against them.
The teacher or “facilitator” of philosophical dialogues does not lead students to a predetermined answer or attempt to validate every opinion as equally sound.

The goal of a philosophical dialogue is not agreement or final resolution, but that all participants be able to decide what each thinks is most reasonable, whether those judgments are in line with the views of a majority or a minority of the other participants or is one student’s view alone.
A philosophy teacher should model and prompt careful thinking within a discussion and help students see the structure of their arguments and encourage them to work towards finding the most reasonable answer.

How do you get started as an educator who wants to philosophize with children?

Many different approaches and tools can be used to ensure that the materials used to inspire philosophical inquiry are age-appropriate:
  • Children’s literature
  • Activities and games
  • Film clips
  • Stories the children bring to the classroom
  • Current events
  • Personal experiences

It is important that the materials used in a philosophy session not only present one or more philosophical themes, but also present them as contestable – preferably, a variety of perspectives on the theme should be represented.


Facilitating philosophy sessions in schools requires someone who is curious and loves thinking about complex ideas, but doesn’t think s/he knows everything!

What should I read to expand my knowledge of philosophy?

The following are some helpful resources for deepening your philosophical awareness.

The Problems of Philosophy

by Bertrand Russell
This slim, classic volume offers an overview of philosophical issues including the nature of reality and the value of philosophy. It does not touch on ethics or social or political philosophy. This work is best for adult readers.

What Does It All Mean? A Very Short Introduction to Philosophy

by Thomas Nagel
Even slimmer than Russell’s classic, this modern overview of philosophical issues is an easy read for most adults and high school students, and probably by many upper-level middle school students. As the author puts it, “This book is a brief introduction to philosophy for people who don’t know the first thing about the subject.” Nagel’s chapters consider nine problems of philosophy, in a very engaging style.

Socrates Café

by Christopher Phillips
Phillips began the Socrates Café movement, which sets up adult philosophy discussion groups at bookstores and other free-access public venues. Phillips’ book is based on the idea that philosophy is something you do –through debate and discussion – rather than simply study, a very appropriate approach for young people. Questions spotlighted in this book include: “What is insanity?” “How do you know when you know yourself?” “What is a world?” “Does anyone have the right to be ignorant?” and “Why question?” Because the tone is colloquial rather than scholarly, it helps those without a philosophy background grasp the nature of philosophical discussion.
