‘Wie niet slim is, moet dom zijn.’ ['Whoever is not clever, should be thick'] In this context, if you don't mind, a quaote from the preface to the Tractatus Logico-Philosophicus by Ludwig Wittgenstein: "Was sich überhaupt sagen lasst, lasst sich klar sagen; und wovon man nicht reden kann, darüber muss man schweigen."
