"In art, theories are as useful as a doctor's prescription; one must be sick to believe them"

This quote by Maurice de Vlaminck recommends that theories in art are only beneficial if they are applied to a particular circumstance. Similar to a physician's prescription, theories in art can just be useful if they are utilized to resolve a particular issue. The quote implies that theories in art are not widely relevant, and that they should be tailored to the specific circumstance. It likewise suggests that a person must be in a state of "sickness" in order to think in the theories. This might indicate that one should be in a state of confusion or unpredictability in order to be open to the concepts presented by the theories. Ultimately, this quote suggests that theories in art are just useful if they are used to a particular scenario, and that one need to be in a state of "sickness" in order to be open to the concepts presented by the theories.
