Jorgensen, Jens Jergen was born on April 1, 1894 in Haderup, Denmark.
Copenhagen.
Although a pupil of Hoffding and at one time lnclined to Neo-Kantianism, Jorgensen developed an interest in logic and the work of the tenna Circle. He wrote a major survey of the evelopment of modern logic and introduced the study of mathematical logic in Denmark. He was °ne of the organizers of the International EncYclopedia of Unified Science and, in his encyclopedic lectures, he sought to instil in his students a general knowledge of the sciences, with a partiular emphasis, according to Neurath. on ‘the grammar of science’. He was hostile to metaphySICs and religion and enthusiastic for the empirical sciences, especially psychology and biology. He las been criticized indeed by Hartnack. among "ers, for taking his preoccupation with pyschol- °gy too far and subordinating logic and philosop y to it. His interpretation of Kant’s epistemology was as the psychology of knowledge. He even held that the principles of logic were based upon psychology, since the human mind might have been structured differently. Hartnack, criticizing Jorgensen’s psychologism, attributes it to the influence of HoITding. It was for his encyclopedic vision of the sciences that Jorgensen was most remembered, both by philosophers internationally and by the huge number of students who attended his introductory lectures during his long period as a teacher at Copenhagen.
