"According to my principles, every master has his true and certain value. Praise and criticism cannot change any of that. Only the work itself praises and criticizes the master, and therefore I leave to everyone his own value"

Carl Philipp Emanuel Bach's quote talks to the intrinsic worth of proficiency in artistry and how it stands apart from external recognition or criticism. The essence of Bach's message is a profound appreciation for the fundamental worth each master has due to their ability, commitment, and distinct contribution to their field. He suggests that this worth is not subject to variation based on appreciation or criticism from others however is steadfast and grounded in the quality and substance of the work they produce.

In saying "every master has his real and certain worth", Bach highlights the idea that proficiency is not specified by popular opinion but by the proficiency and special qualities the master brings to their craft. This viewpoint reinforces the belief that real artistry is self-dependent and does not rely on external affirmation to hold its merit.

Bach further highlights that "only the work itself applauds and slams the master", recommending that the ultimate judge of an artist's worth is the work they produce-- not external voices. The work is a reflection of the master's talent, enthusiasm, and labor. Thus, the development promotes the developer, exposing their strengths and weak points objectively without the predispositions of societal acclamation or ridicule.

The declaration "I delegate everybody his own value" represents a regard for the uniqueness of each master. Bach advocates for allowing each artist's work to base on its own merit, without disturbance. This promotes an egalitarian view of artistry and imagination, acknowledging that every artist's contribution is unique and essential in the grand tapestry of human culture.

In summary, Bach champs a view of artistic stability that values the work itself as the real testament to an artist's skill and worth, independent of fluctuating societal standards or viewpoints. This viewpoint encourages credibility and strength among artists, who are reminded to focus more on their craft than on external recognition.
