ABSTRACT
Those who believe in science must, therefore, accept that they are placing on the evidence of their senses an interpretation for which they must themselves take a considerable amount of responsibility. In accepting science as a whole and in subscribing to any particular statement of science, they are relying to a certain extent on a personal conviction of their own. Science, it is said, does not claim to discover the truth but only to give a description or summary of observational data. Science, free science, can survive in future only by recognising and consciously affirming its true basis: its groundwork of scientific beliefs. Scientists must henceforth profess their adherence to these beliefs by an explicit declaration of faith. Scientists and philosophers who are convinced that science can be based exclusively on data of experience, have tried to avoid the weight of such critical analysis of science by reducing the claims of science to a more moderate level.
