47..."Forget this transcendent certainty, which is connected with your concept of spirit."
In what way is certainty linked to the notion of spirit? — ZzzoneiroCosm
It's a puzzling one. First, it's clear that here and throughout
On Certainty he attacks the notion that ordinary certainty is not enough, that we need, not only a solid bedrock, but one that is is somehow
guaranteed to be solid, for all time and universally, that is, an
absolute certainty. This impossible kind of knowledge would be transcendent, as it would require a foundation external to human capacities.
This is where the concept of spirit comes in, I think. Transcendent (not transcendental) metaphysics is part of what Wittgenstein and others were reacting against in the early 20th century. Passage 47 implies that he sees a connection between the epistemological search for absolute certainty, and transcendent metaphysics such as that of the rationalists. In OC, Wittgenstein is discussing Moore, who was defending common sense against philosophers such as Bradley, for whom the concept of spirit may have been significant, as it was for Hegel, who heavily influenced Bradley. Wittgenstein's word is
Geist, the same as Hegel's. Spirit transcends our everyday reality, and is thus similar to the Holy Grail of epistemology.
Here's the context:
46. But then can’t it be described how we satisfy ourselves of the reliability of a calculation? O yes! Yet no rule emerges when we do so.—But the most important thing is: The rule is not needed. Nothing is lacking. We do calculate according to a rule, and that is enough.
47. This is how one calculates. Calculating is this. What we learn at school, for example. Forget this transcendent certainty, which is connected with your concept of spirit. — Wittgenstein
So calculating according to a rule is enough. Even if it is legitimate to ask if the rule itself is reliable, we shouldn't expect by doing so to find another, higher level, transcendent rule. In the end it is in the very following of the rule that one attains correctness and reliability.
Wittgenstein appears to view this yearning for transcendent truth, rules, knowledge, certainty, and so on, as all connected to the bad philosophical habit, a legacy of theology, that Kant ends up rejecting in the
Critique of Pure Reason. As far as Wittgenstein was spiritual, he regarded it as involving what cannot be said, and therefore as nothing to do with philosophy.
