In so many ways.
First, each one is different. Some collect the newest, the brightest, the most unusual. Some collect historic. Some collect ethnographically used. All are absolutely passionate about what they prefer and why. None of that matters in the long run. Every collector is important. Collectors promote art and creativity. They support artists. They preserve history. They sustain cultural identity. They spark energy that promotes further collecting. The things we collect nurture our souls. And because those things have been collected, and therefore saved for future generations, they nurture other souls after us. Someone--lots of someones--collected the things in the Louvre. And the Smithsonian. In every museum everywhere. How dull would our world be without all those collections?
Collectors are indeed very special people.
