I’m rather skeptical, to say the least, that seeing people’s photographs will make me more interested in their ideas.
To say the most, I actually find that photographs make me less sympathetic. Maybe I’m unusual in this way. I am in plenty of others.
Semi-related: Is it just me who hates advertisements that have photos of smiling or laughing “satisfied customers”? You know, the ones overflowing with euphoria over their new ironing boards? If those things really make an ad more alluring, I guess my reaction to photos is unusual. (Note: I guess I lied when I said I hate such ads. A la Terry Prachett, I’m trough hate and out the other side.)
Apparently, “aletheia” is Greek for truth, and “veritas” is Latin. You can pick either and stick “phile” at the end. So, say, veritophile.
