A rule is || stands there, like a sign post. Does it || the sign post leave no doubt about || as to the || what path I have to take? Does it show in what direction I am || have to go when I have passed it? || ; whether by || along the road, or the field path || along the footpath, or across country || over hedge & ditch? But where does it say in what sense I have || ought to follow it; whether in the direction of the hand or, e.g., in the opposite one || direction? – And suppose instead of one sign post there were || was a closed chain of sign posts, or chalk marks ran || running along ¤ the ground; || : is there only one interpretation for || way of interpreting them? – Then || Therefore I may || can say the sign post || sign-post surely doesn't leave any doubt. Or more correctly || rather: It || it sometimes leaves a doubt, and sometimes not || doesn't. And this is not || isn't a philosophical proposition any more || longer, but an || any longer a philosophical proposition; it's an experiential proposition.
