The Portuguese surname "Spinoza" means "thorny". Beauty is thorny, think of a rose. That is why Baruch de Spinoza designed this seal ring with his initials on the top, a thorny rose in the middle and the Latin word: "Caute" ("Beware"), everything surrounded by 70 points. He used it to close his letters with wax seals.
Girls -- memories, nostalgia, emotions -- are thorny roses. Caute! Sometimes you do not want to grasp them, they wound.
Mecano translated this in a musical language.
