Even those who believe that the art of each age and culture has its own standards of beauty must admit that some painters are simply superior to others in the execution of their artistic visions.
Main Conclusion
The superiority [some painters have relative to others in the execution of their artistic visions] must be measured in light of the artist's purposes.
Premise
The high merits, for example, of Jose Rey Toledo's work and his extraordinary artistic skills are not in doubt.
Opposing Point
[Jose Rey Toledo’s] paintings do not literally resemble what they represent.
