[lit-ideas] Necessity in the Tractatus

In my two previous rambles, I focused on "and"  which is just as well.

A good case to consider is

p v  ~p

or

p & ~p

These are usually regarded, respectively  as tautology and contradiction.

Are they _necessarily_ so. Recall  Sportin' Life, "It ain't necessarily so".

Wittgenstein was pretty  narrow-minded when it comes to things, so he 
possibly thought it _is_  necessarily so.

Strawson prefers to speak of 'logically true' rather than  'necessarily 
true'. We need a Kripke to systematise the uses of 'necessarily'  into 
'logical', 'epistemic' and 'metaphysical' or  ontological.

Cheers,
