J R Kantor, founder of The Psychological Record and its editor for the first five volumes, returned to its pages in 1968 as an essayist under the carefully maintained nom de plume of Observer. The Record had become the principal organ of the school of Interbehavioral Psychology, which he had established, and its universe of interests has continued to expand. The Comments and Queries which Kantor selected for republication in the present volume present his assessment of many trends and problems in contemporary psychology. Furthermore, in them his wide-ranging and integrative thought deals with the place of psychology in the broad range of psychological and philosophical endeavour.
