Actually no, if you fit most of the dictionary criteria then you are an intelectual regardless of what people think?
I don't take the dictionary to be some definitive source for all knowledge. I, like everyone else, makes up their own interpretation of words, and often defines things in different ways. Something that may seem "clear" to brennan may not seem so "clear" to MobBoss, despite meeting one or more of the requirements i the dictionary definition. If you're to live your life by the book (by which I mean dictionary), you will probably end up rather boring and unimaginative, not to mention somewhat detached from the rest of the world.
I personally hate it when people quote lines from the dictionary in support of their opinion. I mean, that's why it's called an "opinion", rather than a "definition".
It doesn't say anything about subjectivity, you either are an intelectual or you aren't, if everyone thought Einstein was a dumb ass would you agree he was a dumb ass? No he was an intellectual and the belief in him or not is nothing to do with it.
I would, as always, have my own opinion on whether Einstein was an intellectual or not. You seem to be prematurely characterising my views on this. So far, I have not seen a satisfactory definition of "intellectual". Sanabas's definition seems rather circular -- it is essentially stating, "you're an intellectual if people perceive you to be an intellectual", since the definition that most people use of what an intellectual is "intelligent". I'm quite content with not defining everything and just calling it when I see it.
Personally, I think the word "intellectual" connotes a sense that the individual has made a career out of thinking or philosophising. Writers immediately spring to mind, as well as philosophers. I see
certain scientists as intellectuals, but in general I don't think that there are many scientists I would class as "intellectuals".
It's all very pretentious.
