This paper examines the almost ineradicable misconception of Wittgenstein's alleged antagonism to science as evidenced through some characteristic disparaging comments by world-renowned scientists, notably by Anton Zeilinger. Above all, he criticizes Wittgenstein on the basis of the opening sentence of the Tractatus Logico-Philosophicus, "The world is all that is the case", which he regards as expressing *"the naive world-view"*1 of a *"typical philosopher of classical physics"*. He proposes an extension in agreement with the findings of quantum theory, namely by the (...) clause *"… and all that can be the case"* (Zeilinger 2003, 231). -/- It will become apparent, however, that this amplification is redundant, that Wittgenstein was in tune with modern physics, that a surprising number of his philosophical concepts are in agreement with it, and that various quantum pundits consider them to be relevant.
