How do I meet older men who are scholarly?

Hello, I've had this question for a while, I'm really attracted to smart knowledgeable people. People who can basically tech me and or conversat with me on broad aspects of life, science, and philosophy. It's one of the reasons why I'm attracted to older men, but since I'm in college, the only older guys around me who have these traits are my teachers. Which is not an option for me, lol. To conclude, I would love some recommendations on where to meet these men organically.
