I’ve always found philosophers a bit intimidating — all that deep thinking, the dense texts, the assumption that you need a PhD to understand them. But then I met David Hume. Not in person, of course — he’s been gone for over two centuries. Still, in the quiet moments of reflection, his ideas feel like a conversation with a thoughtful friend. I first really connected with Hume when I was trying to make sense of my own beliefs, my emotions, and how to live a meaningful life without getting lost in dogma or overthinking everything.

Hume was a Scottish philosopher, historian, and essayist of the 18th century, part of the Enlightenment era that valued reason, experience, and skepticism. But what makes him so relevant today isn’t just his intellect — it’s his approach to life. He believed in living well through moderation, empathy, and understanding the limits of our knowledge. Talking to him — or rather, thinking with him — has helped me simplify my own worldview and find peace in uncertainty.

Here are five life lessons I’ve drawn from David Hume’s writings and how I’ve tried to apply them in my own life.

1. Question everything — especially certainty

Hume famously argued that we should proportion our belief to the evidence. He was deeply skeptical of absolute certainty, especially in matters of religion or metaphysics. He believed that many of our beliefs are based on habit and custom, not reason. This doesn’t mean he was cynical — quite the opposite. He thought we should be honest about the limits of our knowledge.

In my own life, this has helped me be less rigid. When I catch myself thinking “I know this for sure,” I pause and ask, “Do I really? Or is this just what I’ve always believed?” It’s made me a better listener and a more thoughtful person.

2. Let reason serve the passions — not control them

Hume once wrote, “Reason is, and ought only to be the slave of the passions.” He didn’t mean we should be ruled by impulse, but rather that our feelings give meaning to our lives. Reason is a tool to help us act on our values, not dictate them.

I used to think I needed to be purely logical in decision-making. But Hume reminded me that emotions aren’t the enemy — they’re what make life worth living. Now, I try to listen to both my heart and my head.

3. Cultivate empathy — it’s the foundation of morality

Hume believed that our moral judgments come not from reason, but from our ability to feel with others. We approve of actions that promote happiness and disapprove of those that cause harm because we naturally sympathize with others.

When I’m tempted to judge someone harshly, I try to imagine what it’s like to be in their shoes. It doesn’t always change my mind, but it always softens my heart.

4. Live modestly — and enjoy the simple pleasures

Hume was known for his good humor and love of conversation. He lived simply and believed in the value of friendship, literature, and philosophical discussion. He rejected grandiose systems of thought and preferred the company of thoughtful, kind people.

I’ve tried to simplify my life — fewer distractions, more time with people I care about. It’s not always easy, but it’s always worth it.

5. Accept the unknown — and find peace in it

One of the most liberating aspects of Hume’s philosophy is his acceptance of mystery. He didn’t claim to have all the answers — and he didn’t think anyone could. He believed we should live well within the bounds of what we can know.

When I feel overwhelmed by life’s big questions, I remind myself that it’s okay not to have it all figured out. The search itself can be enough.
