Answer:
If you make insightful comments, this will help to give the reputation of being an intellectual. But before you are in a position to make insightful comments you will probably need to read many books, to become broadly educated in many subjects, and to think about what you are learning, so that you can form your own opinions, rather than just repeating what others have said. Intellectualism develops from a love of knowledge. Those who do not love knowledge but who want to have the social status that comes with intellectualism, may wind up merely as pseudo-intellectuals.
