The ‘Mastermind’ edition is a symbol for all progressive thinkers and visionaries in the multifaceted world that is art. They all share one trait: their above-average capacity to imagine, which allows them to cross borders, bridge divides, create links, and characterise entire generations. If we were to take a closer look, we’d spot another important trait: they need someone to believe in and stimulate them. As the Medici Family in Florence did by supporting artists, philosophers, literates and musicians. Patrons, benefactors, and sponsors are still necessary today to translate visions into reality. Napoleon Hill describes this principle as the Master Mind principle. ‘The Master Mind principle: two or more people actively engaged in the pursuit of a definite purpose with a positive mental attitude, constitute an unbeatable force.’ That’s why MilionArt Kaleidoscope 3.17 is not only dedicated to all progressive thinkers, but also to those people who support them. The bigger we think, the braver we have to be, and this courage is not only to be found in visionaries but also in those people who believe in them.
