“In Popper's opinion, the program can be fairly described as totalitarian. He noted some objections to that verdict, such as Plato's desire for Goodness and Beauty, and his love of Wisdom and Truth, and the idea that the wise should rule, rather than the strong or a hereditary monarch. And above all is the idea that the state should be founded upon Justice. These objections reflect the tendency to interpret Plato in the best possible light, even on the part of writers who were clearly aware of the totalitarian tendencies in his thinking. Popper defended equalitarian justice by which he meant equality before non-discriminatory laws and an equal distribution of the limitations on freedom that are required for a functional society.”

“And this led Schlick to formulate a succinct moral principle: “Sei glücksbereit! ” or, rendered literally in English, “Be ready for happiness!” The spirit of the remark, however, is perhaps more accurately caught by the less compact phrase “Always be ready to give happiness a chance!”

“This term serves to contrast our worldview with philosophy in its usual sense, as a doctrine about the world that claims to stand side by side with the scientific disciplines, or possibly even above them. In our opinion, anything that can be sensibly said at all is a proposition of science, and doing philosophy just means examining critically the propositions of science to check whether they are or are not pseudo-propositions (that is, whether they really have the clarity and significance ascribed to them by the practitioners of the science in question); and it means, further, exposing as pseudo-propositions those propositions that lay claim to another type, and a higher degree, of significance than the propositions of science.”

“To make matters even worse, Schlick had the cheek to write an essay called “The Meaning of Life.” He even gave a simple answer to the question. The meaning of life does not reside in a higher purpose, but can be expressed in just one word, said Moritz Schlick: “The meaning of life is youth.”
