Study of the man is a worthy and valuable thing to do, in the right context and time/place. There is absolutely zero value to erecting a statue of the man, as a person. In fact, it ossifies the man and his works/thoughts, rather than allowing us to continue to evaluate the man and his doings in light of an evolving and changing society. Again, the statue has zero intrinsic value, and has a very real possibility of making his equals feel like outsiders or outcasts. What possible value does the statue provide? Nothing.
I'm sure you've been to Washington DC. I'm sure you've seen the monuments of our founders and those that shaped our countries history. When you were there did the statues make you feel like an outsider or an outcast? Honestly? That's so foreign to me. When I see the statue of MLK I am embolden towards his greatest virtues. When I see the statue of FDR in his wheelchair, and the statue of a family listening to a fireside chat of his, I am reminded that a person, a handicapped man (yes, old and white), helped to steer a country through incredibly dire times. A human. It's right to celebrate each other as humans. I cannot even believe that I am having to have a discussion about it being right and proper to use the art form of sculpture to represent human struggle and achievement. Art has amazing intrinsic value. This statue that started this discussion was commissioned by a Jewish man that felt indebted to Jefferson for fighting for religious freedoms. That story alone has intrinsic value. The debate that this statue has stirred up has intrinsic value. I can understand having a debate as to weather or not Thomas Jefferson's misdeeds should make us rethink his place in history. But debating the intrinsic value of sculptures of the human experience/form is, to me, bonkers.
The only statue in DC that had any effect on me at all, was the Lincoln Monument. It is awe inspiring, and the quotes on the walls are poignant even today. Every other statue was devoid of context or message. Which Roosevelt was it in a wheelchair? Which one implemented the New Deal? Which one didn't shoot a bear? No idea. Just more men on pedestals, devoid of valuable information or context. But I was moved to tears at the Vietnam Veterans Memorial. (As I was at the 9/11 memorial in NYC, too.) The grave of the Unknown Soldier is a powerful monument with a gravity and apparent purpose that inspires visitors to speak in a whispered hush. THAT's good statuary/art/monumenting; the message is apparent and powerful, regardless of the era it is viewed in, or the people involved.
