Quote by Marcel Proust
No exile at the South Pole or on the summit of Mont Blanc separates us more effectively from others than the practice of a hidden vice.

Summary
This quote expresses the idea that engaging in a secretive vice creates greater distance between ourselves and others than even physical remoteness. It suggests that indulging in a hidden vice, such as a bad habit or immoral behavior, isolates us from society in a profound way. Regardless of our physical proximity to others, the act of concealing and participating in a vice alienates us, reinforcing the idea that breaking free from such behavior is necessary to truly connect with others.
