Justification and Best Means

The substantive question to a Marxist regarding the Justification of Means is: Is revolution the best means to a Socialist state?  Implicit in that formulation is the possibility of alternative means.  Hence, the question is inapplicable when Revolution is conceived as a transition in a Necessary process.  Likewise remaining implicit in the Marxist answer is that one alternative--a universally voluntary collectivization of the Means of Production--may be extremely unlikely.  But, even if so, it is not logically impossible, which is why a Philosophical examination of Marxism requires that that alternative, and any others, be explicitly addressed, before being dismissed.
