"I've never tried to learn the art of acting. I have been in the business for years but I still can't tell what acting is or how it's done"

Paul Muni's quote shows an extensive humility and acknowledgment of the enigmatic nature of acting, even from somebody who had a successful profession in the film industry. Muni, an actor renowned for his flexible functions and dedication to his craft, is revealing an awareness that acting is not an exact science or a fixed skill set that can be fully mastered, even with years of experience.

His declaration "I've never attempted to find out the art of acting" can be interpreted as a recommendation that acting is not something that can be comprehensively learned or taught in a conventional way. Instead, it suggests that acting is a deeply individual and evolving practice. Each function may require different attitudes, emotions, and expressions, therefore making the star continuously adapt and find new elements of their capability and imagination.

The 2nd part of the quote--"I have actually remained in business for several years however I still can't inform what acting is or how it's done"-- highlights the mystical and instinctual components of acting. Muni seems to convey that acting is less about understanding and more about being-- inhabiting a character and connecting authentically with the human experience. His words recommend that while technical abilities such as memorization and physicality are important, the core of acting involves a natural, instinctive understanding of human habits and feelings that can't be totally deconstructed or discussed.

Moreover, Muni's perspective emphasizes that each actor might have their unique technique or understanding of their craft. What works for one may not work for another, strengthening the concept that acting is subjective and deeply personal. It's an art kind that balances preparation with spontaneity and knowledge with instinct. This understanding from someone of Muni's stature motivates both present and hopeful stars to embrace the unpredictabilities and expeditions intrinsic in their craft and advises them that the essence of acting depend on its ability to catch the unforeseeable essence of life itself.
