The remainder, after science
On the axis: Place of science · the questions of life
Science tells the how, never the why or what is worth doing: it could answer all its possible questions without having even touched what gives a life its meaning. Are there truths, about meaning or the good, beyond its reach?
Justification
Wittgenstein is not against science, but against scientism: the idolatry of method, of "progress" and of generality, projected onto philosophy. The philosopher who "craves generality" and despises the particular case apes science; but philosophy, ethics and religion are distinct language-games, not deficient sciences. He even doubts that "the age of science and technology" is where the human finds its meaning.
