Condition of knowledgeThis book is translated from Israel Schefflers The Conditions of Knowledge, published in 1965. The author attaches subtitle to epistemology and establishment for education, and discusses in depth the argument that it examines the problem of knowing in education from the viewpoint of epistemology in earnest. This book focuses primarily on the theoretical knowledge and philosophically demonstrates the conditions under which this knowledge is established. In addition, the issues and issues arising from the process are closely examined in the educational context.Knowledge problem is a key issue in education as a whole and educational philosophy is not different. The problem of knowledge which is discussed in the philosophy of education is not the same as the philosophy of education which is the result or method of inquiry of general philosophy or traditional philosophy. Educational philosophy inquiry should be centered on the epistemological questions that are found in the field of educational practice, namely, the nature and value of the knowledge related to the subject, the problem of the generation of knowledge related to learning, and the problem of effective knowledge transfer caused by the teaching process. This book is a leading book that meets this purpose.
