A person who has epistemophilia; someone with a strong, almost passionate love of acquiring knowledge and understanding.
From Greek 'episteme' (knowledge) + 'philia' (love) + '-ac' (a person with), directly describing someone driven by the desire to know, used in psychology and personality studies.
If you find yourself reading encyclopedias for fun or going down Wikipedia rabbit holes for hours, you might be an epistemophiliac—and that's actually a compliment.
