Welcome to the Tumistic Institute podcast. Our mission is to promote the Catholic intellectual tradition in the university, the church, and the wider public square. The lectures on this podcast are organized by university students at Tumistic Institute chapters around the world. To learn more and to attend these events, visit us at

changes, okay? And this includes when we form habits. So when we form habits, the brain changes.

And that vice and virtues are habits,

as defined by Aquinas. And then we're just going to, because the talk is relatively short,

we're just going to focus on two related virtues and two related vices. So we're going to focus on

humility and magnanimity as the two virtues.

And then we're going to focus on two vices, pride and vain glory. And then we're going to look at

some practical steps and how we can grow in these things.

So the brain, I've dedicated much of my life to studying this and trying to fix the brain when things go wrong with it.

That's my main job as a neurologist.

And the brain is just overwhelmingly complex for anyone. There are 86 to 100 billion neurons in the human brain.

And every neuron has potentially 10,000 connections,

which means there is a quadrillion connections in the brain,

which is just staggering.

We think of neurons as maybe just one thing,

but there are actually hundreds of different types of neurons as well

that have different functions.

We don't understand how they all work.

There's much that we don't understand. When we think about neuroscience, there's what we actually know, and we know a ton.

We can fill libraries with information of what we know about the brain, but then there's

also what could potentially be known.
