Arguments Concerning the Criterion of Truth in the Modern History of Philosophy in Western Europe
The thesis that social practice is the only criterion by which to judge truth has now become common sense in Marxist philosophy. However, the formulation of the thesis came as a result of the long period of exploration and struggle over the issue of the criterion of truth in the history of human knowledge. In Europe, the criterion has varied from the scholasticism of the Middle Ages, through the capitalist philosophy of modern times, to Marxist philosophy, according to the different philosophical lines and different viewpoints on truth. In a nutshell, in the Middle Ages, the criterion was the religious inquisition based on dogmas in the "Bible." In opposing the ecclesiastic theology of the Middle Ages, capitalist philosophers in modern times presented "judgment by rationality." On the issue of the criterion of truth, some of them stressed rationality, while others emphasized experience. Only when Marxist philosophy proposed judgment on the basis of social practice was the issue truly resolved scientifically.
