Therefore of necessity they must at first believe that Felicity is a glorious though an unknown thing. And certainly it was the infinite wisdom of God that did implant by instinct so strong a desire of Felicity in the Soul, that we might be excited to labour after it, though we know it not, the very force wherewith we covet it supplying the place of understanding. That there is a Felicity, we all know by the desires after, that there is a most glorious Felicity we know by the strength and vehemence of those desires. And that nothing but Felicity is worthy of our labour, because all other things are the means only which conduce unto it. I was very much animated by the desires of philosophers, which I saw in heathen books aspiring after it. But the misery is It was unknown. An altar was erected to it like that in Athens with this inscription: TO THE UNKNOWN GOD.
