How do people discover if their beliefs are true or false? Philosopher Peter Singer, an emeritus professor of bioethics at Princeton University and co-editor of Journal of Controversial Ideas, argues that this can only happen through free debate of controversial issues. In this short six-minute video, Singer examines the consequences of censorship and explains why we need to get more comfortable debating uncomfortable questions.
- In this video, Singer gives two examples (Rebecca Tuvel and Jeremy Bentham) to illustrate what happens when controversial ideas are suppressed. Pick one of these examples and explain how Singer uses that example as evidence to support his main argument. Do you think this is a good example for his argument? Why or why not?
- So what? Who cares? According to Peter Singer, what happens when open debate about an issue is suppressed? What are the consequences to individual people, to society, and to the pursuit of knowledge and truth?
- Many of the points in Singer’s argument focus on why faculty need to have spaces to openly debate ideas. Consider the perspective of students, especially students on your campus. What spaces exist to critically examine controversial issues? What policies, programs, or conditions support free and open debate of controversial ideas? What might prevent students from making an unpopular argument or raising a controversial question?
- Some might argue against Singer’s argument and say that there should be limits on the kinds of questions or ideas made in academic spaces, like universities, college classrooms, or academic journals. What might these limits be? Compose your own response to Singer’s argument. Do you agree, disagree, or both? In your response, you can reference the points made in the ACLU’s open letter about student protests or PEN America’s Campus Free Speech Guide.

I agree with Rebecca Tuvel because, People should love the person they are with. If its a different gender then that should be okay. Other people will judge but like the phrase says “you can’t judge a book by its cover”. A lot of people will start out by being straight but then turns out that they want to be with the other gender more. I also agree with singers evidence. In Jeremy part, he said “Jeremy never publish the article until this century”> But people were already dating the same gender by then.

Both examples are great if you give them a thought. Both are controversial, and if we as a society would give them a chance to actually think about them and not just follow what is being imposed, most of the barriers and oppositions would see their mistake. On the identity side, I believe everyone has a right to feel however they want to feel, but should not impose their thought on others; it will be the same problem that they were suffering, just changing sides. Also, acknowledge that even though they feel/ believe something, that doesn’t make it true or real. Biological women will always be biological women; the same goes for men.

Peter Singer uses the example of Rebecca Tuvel to show how people can be attacked for asking difficult questions. Tuvel wrote about identity, and instead of open debate, she faced harsh backlash. Singer says this is a problem because without debate, we can’t test if our ideas are right or wrong. I think this is a good example because it shows how fear can stop people from speaking up. On my campus, there are some spaces to talk about hard topics, but a lot of students stay quiet because they don’t want to be judged. I mostly agree with Singer, but I think there should still be some limits, like no hate speech or targeting people.

After watching Peter Singer’s discussion, I found myself agreeing with his main argument that people should not be afraid to question ideas or discuss controversial topics. One example that stood out to me was his discussion of Rebecca Tuvel. Singer explains that instead of responding to her article with evidence or thoughtful counterarguments, many people demanded that it be withdrawn simply because they disagreed with the questions she raised. I agree with Singer that this is the wrong approach. If we stop people from asking difficult questions, we also lose the opportunity to examine whether our own beliefs are actually true. After reading Rebecca Tuvel’s own reflections on the controversy in a 2026 interview with Justin Weinberg, I realized her experience reinforces the very point Peter Singer is making. Looking back on what happened, Tuvel explains that the experience changed the way she thinks about philosophy and justice. Rather than believing philosophy should simply support conclusions people already agree with, she now believes it serves justice best by pursuing the truth, even when that truth is uncomfortable. What stood out to me most was her observation that “a constitutive feature of being in an echo chamber is that you don’t know you’re in an echo chamber.” That statement really made me think because it reminds us how easy it is to believe we are open-minded while never seriously questioning our own assumptions. This idea connects to one of the biggest lessons I have learned throughout my Critical Thinking class. Our beliefs become stronger when they are tested, not when they are protected from criticism. If we only surround ourselves with people who already agree with us, we never have to defend our reasoning or consider another perspective. That may feel comfortable, but it does very little to help us grow intellectually. I believe colleges should be places where students are encouraged to ask difficult questions, examine evidence, and respectfully challenge ideas without immediately being judged or silenced. At the same time, I understand why controversial discussions can make people uncomfortable. Some topics are deeply personal and connected to people’s identities and life experiences. Respect should always be part of those conversations. However, I do not believe respect and open debate are opposites. There is an important difference between attacking a person and challenging an idea. Universities should encourage students to do the second while making it clear that personal attacks have no place in academic discussion. In the end, I agree with both Singer and Tuvel that education should be a place where ideas are tested rather than suppressed. History has shown that many beliefs once accepted as unquestionable were later challenged and changed because people were willing to ask difficult questions. If students become afraid to speak because they fear being attacked instead of challenged, everyone loses the opportunity to learn. To me, critical thinking is not about proving that we are right. It is about having the humility to question our own assumptions, listen to different perspectives, and follow the evidence wherever it leads.
