In the most general sense, a process involving opposites (for example, one might say that history is a dialectic of spontaneity and constraint); more narrowly, a process resulting in a synthesis or reconciliation of opposing forces or factors.
A process by which one element, the thesis, is contradicted by an opposing element, the antithesis. This contradiction is resolved by a synthesis of the thesis and antithesis. The synthesis then becomes the new thesis and the sequence repeats. This is the process by which Marx believes history proceeds, a dialectic of class antagonism. The proletariat victory will be an end to the dialectic and thus an end to history.
Dialectic is a term referring to a dynamic tension within any given system and the process by which change occurs on the basis of that tension and resulting conflict. Based on the writings of Hegel, every concept implies its negation; that is, in conceiving anything (thesis), we must be able to imagine its opposite (antithesis).
1. The art or practice of arriving at the truth by disclosing the contradictions in an opponent's argument and overcoming them. 2. The Hegelian process of change whereby a thesis is transformed into its opposite, an antithesis…the combination of the two being resolved in a higher form of truth. 3. A method of argument or exposition that systematically weighs contradictory facts or ideas with a view to the resolution of their real or apparent contradictions.
In classical philosophy, dialectic (Greek: Î´Î¹Î±Î»ÎµÎºÏ„Î¹ÎºÎ®) is an exchange of propositions (theses) and counter-propositions (antitheses) resulting in a synthesis of the opposing assertions, or at least a qualitative transformation in the direction of the dialogue. It is one of the three original liberal arts or trivium (the other members are rhetoric and grammar) in Western culture. In ancient and medieval times, both rhetoric and dialectic were understood to aim at being persuasive (through dialogue).
