“The search for truth is more precious than its possession.”

“The true value of a man is not determined by his possession, supposed or real, of Truth, but rather by his sincere exertion to get to the Truth. It is not possession of the Truth, but rather the pursuit of Truth by which he extends his powers and in which his ever-growing perfectibility is to be found. Possession makes one passive, indolent, and proud.”

“For me the greatest beauty always lies in the greatest clarity.”

“Nicht die Wahrheit, in deren Besitz irgend ein Mensch ist oder zu sein vermeinet, sondern die aufrichtige Mühe, die er angewandt hat, hinter die Wahrheit zu kommen, macht den Wert des Menschen.”

“«Vedete, così la penso io: se al beneche vorrei fare si avvicina troppoun grande male, allora preferisconon fare affatto il bene. Perché il malenoi sappiamo benissimo qual è,il bene molto meno.»”

“Laß uns faul in allen Sachen, nur nicht faul zu Lieb und Wein, nur nicht faul zur Faulheit sein.”

“Ein Hurenhaus geriet um Mitternacht in Brand.Schnell sprang, zum Löschen oder Retten,Ein Dutzend Mönche von den Betten.Wo waren die? Sie waren – – bei der Hand.Ein Hurenhaus geriet in Brand.”
