This final presentation focused on the chapters of Why Grow Up by Susan Neiman that were titled What is Enlightenment and Breaking Chains. However, I wanted to really focus on the comparisons of how Immanuel Kant and Jean-Jacques Rousseau think of growing up and how it’s transferred to modern times. However, I found this article for those who want to learn more about how they affected the Enlightenment. Otherwise, let’s have a relaxed conversation on growing up. Feel free to respond to this however you want!
Growing Up: What Kant and Rousseau Can Teach Us About Becoming Human
Growing up is weird. One minute you’re convinced the world revolves around you, and the next you’re filing taxes and worrying about finals. But while we’re all busy figuring out adulthood on the fly, two philosophers, Jean-Jacques Rousseau and Immanuel Kant, were thinking deeply about what it really means to grow up long before self-help books became a thing.
Their ideas are surprisingly relevant today, especially for anyone trying to understand childhood, adulthood, or why becoming a mature human sometimes feels like assembling IKEA furniture without instructions.
Let’s unpack those ideas in somewhat simple references.
Rousseau: The “Let Kids Be Kids” Guy
If Rousseau had a parenting style, it would be something like:
“Relax. Stop hovering. The kid’s fine.”
Rousseau believed children are naturally good, little sparks of curiosity and innocence just trying to explore the world. According to him, society is what messes them up. The rules, the comparisons, the pressure to grow up too fast, he saw all of that as a fast-track to inauthenticity.
Rousseau was adamant that childhood matters for its own sake. Kids shouldn’t be rushed into becoming mini-adults. They learn by touching, playing, messing up, and trying again. Not by adults lecturing them about how “they’ll understand when they’re older.”
“A free child only submits to the necessity of things, not to the other people’s wills” (Neiman 62).
He would be firmly against flashcards for infants and that competitive-parenting thing where everyone brags about their toddler’s “leadership potential.”
Instead of punishment, Rousseau thought children should experience natural consequences. You break your toy? Well, now you don’t have a toy. You refuse to wear a coat? Okay, you’ll be cold. Lesson learned. He shows this very clearly in Emile, saying that the child only needs to follow natural limits.
To him, real growth comes from experiencing the world directly, not from adults imposing their anxieties on kids.
For Rousseau, the ideal adult stays connected to their natural self, someone who feels, cares, explores, and acts with sincerity. Growing up doesn’t mean becoming someone society wants you to be; it means becoming more authentically you.
Kant: The “Take Responsibility for Your Life” Guy
If Rousseau is the free-range parenting advocate, Kant is more like the parent saying,
“You can do whatever you want… as long as it’s the right thing.”
Kant believed growing up is all about learning to think for yourself, not in a “rebel without a cause” way, but in a responsible, moral way. Kant has this famous line about enlightenment being humanity’s escape from “self-incurred immaturity.” In normal-person terms, that means:
Stop letting other people tell you what to think.
He thought maturity was tied to autonomy, the ability to guide your life using reason rather than impulse or peer pressure. If Rousseau wants us to stay true to nature, Kant wants us to level up with reason.
Kant doesn’t hate freedom; he just thinks it has to be earned. Kids start out impulse-driven (I want candy now, not later). Before they can handle freedom, he says, they need structure: learning to wait, follow rules, and practice self-control. To Kant, discipline is a preparation for real freedom. It’s training wheels for moral decision-making.
When Kant imagines the ideal grown-up, it’s someone who acts with purpose, considers other people’s needs, and lives according to principles they genuinely believe are right. Not because someone told them to. Not because they “felt like it.” Because they’ve thought it through.
Where They Agree (and Don’t)
Rousseau and Kant are like two friends giving totally different advice, yet both making valid points. Even Neiman points this out with her own comparisons of both of the authors’ lifestyles, saying, “On the surface, the only thing the two men had in common was class background…in every other way Kant and Rousseau seem different souls” (Neiman 43). So where do they agree and where don’t they agree?
What They Agree On:
Both philosophers agree that growing up is a journey toward becoming a full human being, that kids aren't adults and shouldn't be treated like they are, and that freedom matters, but how and when it's introduced is key.
Where They Differ:
Rousseau says to trust nature and let kids grow without interruption so they can be authentic. For him, freedom is the starting point. Kant says to trust reason, while kids grow with structure to become responsible adults who know how to be moral. For him, freedom is the destination.
Basically, Rousseau wants you to stay connected to your inner child; Kant wants you to manage that inner child responsibly. Together, they shape a really cool picture of maturity: You’re born with natural goodness and curiosity; however, you need discipline and reasoning to turn that into stable adulthood.
Why This Matters Today
Even though these two lived in the 1700s, with no internet, no screen-time debates, no helicopter parents, they shaped a lot of the ideas we still use to think about childhood and adulthood today. From Rousseau, we get child-centered education, emphasis on creativity and exploration, respect for children’s emotions, and the belief that childhood shouldn’t be rushed. From Kant, we get moral education (more or less), lessons on responsibility, helping kids learning independently, and the idea that real freedom involves self-control. Modern parenting, schooling, and youth development are basically a tug-of-war between their ideas. And honestly? We probably need both sides. Kids need room to explore and be themselves. But they also need guidance so they can become adults who don’t ghost their responsibilities, or people.
So What Does It Mean to “Grow Up” Really?
If we blend Kant and Rousseau together, growing up looks something like this:
- Start with curiosity and freedom.
- Experience the world directly.
- Learn from consequences (natural and logical).
- Build discipline and self-control.
- Develop your own principles.
- Become someone who acts with authenticity and responsibility.
Not a bad roadmap.
Growing up, then, isn’t just about getting older or checking off milestones. It’s about balancing our natural, childlike selves with the rational, principled selves we grow into. It’s not just nature or discipline. Not just feelings or reasoning. Not just childhood freedom or adult responsibility. It’s the ongoing dance between both.
Final Thought: Becoming Human Is a Lifelong Project
Rousseau reminds us to stay grounded in our natural humanity. Kant reminds us to rise into our moral potential. And somewhere between those two poles is the messy, beautiful process of becoming an adult.
Growing up isn’t a one-time event; it’s a lifelong project. You don’t finish it at 18. Or 30. Or even 60. Maybe to grow up well is to keep that inner child alive, curious, open, and honest, while building the inner adult who can steer that energy with purpose.
If Rousseau gives us the heart, Kant gives us the compass. And we probably need both to navigate the wild adventure of being human.
My final question to you is, how do you think Rousseau and Kant have influenced our modern lives?
