"Siqueiros is the best proof that a really great painter has, above all, a social consciousness and an ideological conviction. The greater the conviction, the greater the painter... Siqueiros is the splendid synthesis of the conception of the masses and an individually perceived representation of that concept. Between the emotional explosion and the disciplined intellect, Siqueiros strikes a blow with his brush with the implacable certainty of a pneumatic drill on the path leading to the final goal that he always has in sight."
