ABSTRACT
On Marx's tomb in a London cemetery are carved his words: 'Philosophers have only interpreted the world in various ways; but real task is to alter it'. He succeeded more than he realized. Subjectively, every philosopher appears to himself to be engaged in the pursuit of something which may be called 'truth'. Philosophers may differ as to the definition of 'truth', but at any rate it is something objective, in some sense, everybody ought to accept. No man would engage in the pursuit of philosophy if he thought that all philosophy is merely an expression of irrational bias. One thing is certain – that effective progress depends upon programmes realistically adjusted to local and topical needs. People will agree on programmes when they will fight battles over principles. Policy gradually shapes itself as satisfactory achievements are reached. It is then that provisional working principles is formulated, compared, and analysed. It is that philosophy is vindicated as a criterion of comparison.
