How to connect with professors as a non-academic? Long story short, I could never attend higher education, and now, later in life, I would love to be with people 100x smarter than me that take a scientific approach to discussions. Professors seem like good candidates. My girlfriend recently finished her PhD(albeit in a different field than I'm interested in) and interacting with her professors and advisors felt like such a stimulating environment. I would absolutely love to find myself in such an environment.

My question is: I want to contact professors, perhaps attend lectures, and I'd REALLY like to eventually try and develop some sort of mentorship, but I'm completely outside academia. Is this absolutely impossible? Studying is a bit complicated, as my level of the local language is A2, and I need B2 to enrol in a bachelor's, so I'd only be able to attend lectures from Master's level and upwards, which are taught in English.

The topics are psychology/political science/philosophy/neuroscience.

Any tips?
You could try to select a precise topic, collect related scientific articles on Google Scholar from universities located in the country or city you live in, see if their authors have social media accounts (Twitter, Facebook, LinkedIn), add, follow or connect (to) them, read the articles and start asking questions to the authors.
