The more you learn about anything, the more you realize you have yet to learn. To be truly intellectual is to be humbled by the many times your ideas have not survived analytical and scientific rigor.
For this reason, this dogmatic, dismissive attitude is not one I associate with an "intellectual" and therefore this person ceases to be one in my mind.

You can study in the same field your whole life and still lie on your death bed in awe at what you don't know.
