kilosopher
A kilosopher is a philosophical poser: a person who can recite large amounts of information, but lacks comprehension and therefore cannot offer any in depth analysis.
A kilosopher might be a college freshmen who, after a philosophy 101 course, can parrot his/her teachers to impress his/her friends, but, when pushed to go deeper into the material or look at it from a different angle, he/she changes the subject.
