Isiah Berlin, in [Ber78], quoted the Greek poet Archilocus:
The fox knows many things, but the hedgehog knows one big thing.using this to distinguish different kinds of philosophical thought.
In these terms Wittgenstein began with his Tractatus as a hedgehog, and having exhausted this mode of thought was the better equipped to show its illusory nature. In his later re-incarnation as a fox, Wittgenstein:
described the sources of error, the roots of philosophical confusion, the temptations of metaphysical illusion, the irresistable allure of apparently sublime logical insight, with a depth of understanding and richness of detail unparalleled in the history of the subject.in the Philosophical Investigations. Frank Ramsey observed [Ram78] that in long standing philosophical disputes:
it is a heuristic maxim that the truth lies not in one of the two disputed views but in some third possibility which has not yet been thought of, which we can only discover by rejecting something assumed as obvious by both the disputants.
This was done by Wittgenstein many times over:
Wittgentein repudiated reductive and constructive analysis in favour of connective and therapeutic analysis.
