All right, so here's where we were yesterday.

I told you Aquinas' ethical theory has its heart relationship.

The primary relationship is between God and a human person,

but also that is a shareable relationship,

and that relationship is a relationship of love.

Aquinas thinks you can distinguish between big goods and little goods and here's how

you can distinguish between them. Big goods don't diminish when you distribute them.

So if I distribute pizza, my pizza diminishes as I hand it out. I have less and

less pizza in my box, the more pizza I give to you. But knowledge is not like that, so I can

distribute what I know to you, and I don't get stupider when I do so. That makes knowledge a big good

and pizza a little good.

The biggest good of all is love in union with God,

and therefore that is also the most shareable good.

So that's the heart of the human moral life,

that's the heart of human excellence.

A second personal relationship with God,

shareable with all of the human beings too.

And here's the interesting thing.

Aquinas has an account of love, which is, in my view, brilliant.

I'm not saying he invented it, but he has a nice clear way of presenting it.

And it's better than any other account of love I know,

certainly better than any account on offer
