A Mathematical proposition (n.) has a role in which believing does not occur, as one does not believe the rule of castling but that the rule runs so.
A Mathematical proposition (n.) has the dignity of a rule; it moves from rules of our language to other rules, which gives it an unassailable, set-apart solidity.
A Mathematical proposition (n.) that is never applied is an architrave hanging in the air, supported by nothing and supporting nothing.
A Mathematical proposition (n.) seems to point at a reality outside itself, but only expresses the adoption of a new measure of reality.
A Mathematical proposition (n.) is no more anthropology than a statute book is a report on how a nation treats its thieves; the judge does not use it that way.
A Mathematical proposition (n.) stands on four feet, not three: it is over-determined.
A Mathematical proposition (n.) is acknowledged by turning our back on it: we rest, or lean, on its rigid connections.
A Mathematical proposition (n.) is the fixing of a concept after a discovery: I find not the result, but that I reach it.
A Mathematical proposition (n.) known is not yet knowledge of anything: if we agree on it we have only set our watches, not measured time.
A Mathematical proposition (n.) says to me: proceed like this!
A Mathematical proposition (n.) can be imagined as a creature that itself knows whether it is true or false.
A Mathematical proposition (n.) is an allusion to a proof.
A Mathematical proposition (n.) says what its proof proves and never more.
A Mathematical proposition (n.) is the visible surface of a body of proof, the boundary facing us.
A Mathematical proposition (n.) is a pointer to an insight; without one it would be utter nonsense.
A Mathematical proposition (n.) is denied solitary glory; it must belong to a calculus and mix with others.
