We are always hearing of people who are around seeking after the Truth. I have never seen a (permanent) specimen. I think he has never lived. But I have seen several entirely sincere people who thought they were (permanent) Seekers after the Truth.

That was the end of the search. The man spent the rest of his hunting up shingles wherewith to protect his Truth from the weather.
