Tracing the interplay between theory and practice in the dynamics of philosophical argument, This paper represents philosophy as an open, Critical discipline, Which keeps asking the same fundamental questions about knowledge, Reality, Justice, Freedom, Harmony and truth under changing historical conditions. In the light of this, The present impasse of human thought which manifests itself in the confrontation between totalitarian functionalism in the west on the one hand and totalitarian ideologism in the east on the other, The need for a (...) reversal of thinking becomes evident. The present deadlock of human thought and the confrontation between west and east resulting from it can be broken only if one-Sided functional practice is replaced by fully-Fledged human practice. This requires moving beyond popper's one-Dimensional 'critical' rationalism and marxism-Leninism's 'scientific' dialectical materialism to a critical humanism, Based on man's contingent experience of reality.
