lots of people are remembered for being well read. Take someone like Noam Chomsky. He has written many books based on facts he has read, remembered, and used to support his point of view. his opinion is included, but it is always supported by countless examples and recitation of facts. I have friends that read everything and know a lot on most subjects that intrest me. I admire that a lot, and it is always refreshing to converse with them and learn new things. Some people have the skill of great memory and ability to conjure up information at the right time to create powerful statements.
