A good taste in art feels the presence or the absence of merit; a just taste discriminates the degree--the poco piu and the poco meno. A good taste rejects faults; a just taste selects excellences. A good taste is often unconscious; a just taste is always conscious. A good taste may be lowered or spoilt; a just taste can only go on refining more and more.
