or it doesn't", and the very thing that is in question is what "tallying" is here.
200. Really "The proposition is either true or false" only means that it must be possible to decide for or against it. But this does not say what the ground for such a decision is like.
20 Suppose someone were to ask: "Is it really right for us to rely on the evidence of our memory (or our senses) as we do?"
202. Moore's certain propositions almost declare that we have a right to rely upon this evidence.
203. [Everything that we regard as evidence indicates that the earth already existed long before my birth. The contrary hypothesis has nothing to confirm it at all.
If everything speaks for an hypothesis and nothing against it, is it objectively certain? One can call it that. But does it necessarily agree with the world of facts? At the very best it shows us what "agreement" means. We find it difficult to imagine it to be false, but also difficult to make use of.]{crossed-out in MS}
What does this agreement consist in, if not in the fact that what is evidence in these language games speaks for our proposition? (Tractatus Logico-Philosophicus)
 Giving grounds, however, justifying the evidence, comes to an end; - but the end is not certain propositions' striking us immediately as true, i.e. it is not a kind of seeing on our part; it is our acting, which lies at the bottom of the language-game.
 If the true is what is grounded, then the ground is not true, not yet false.
 If someone asked us "but is that true?" we might say "yes" to him; and if he demanded grounds we might say "I can't give you any grounds, but if you learn more you too will think the same."
If this didn't come about, that would mean that he couldn't for example learn history.
 "Strange coincidence, that every man whose skull has been opened had a brain!"
 I have a telephone conversation with New York. My friend tells me that his young trees have buds of such and such a kind. I am now convinced that his tree is... Am I also convinced that the earth exists?
The existence of the earth is rather part of the whole picture which forms the starting-point of belief for me.
 Does my telephone call to New York strengthen my conviction that the earth exists?
