Largely unacknowledged by historians of the human sciences, late-19th-century psychical researchers were actively involved in the making of fledgling academic psychology. Moreover, with few exceptions historians have failed to discuss the wider implications of the fact that the founder of academic psychology in America, William James, considered himself a psychical researcher and sought to integrate the scientific study of mediumship, telepathy and other controversial topics into the nascent discipline. Analysing the celebrated exposure of the medium Eusapia Palladino by German-born Harvard (...) psychologist Hugo Münsterberg as a representative example, this article discusses strategies employed by psychologists in the United States to expel psychical research from the agenda of scientific psychology. It is argued that the traditional historiography of psychical research, dominated by accounts deeply averse to its very subject matter, has been part of an ongoing form of ‘boundary-work’ to bolster the scientific status of psychology.

We are ignorant knowers. This paper proposes an information theoretic explanation of that fact. The explanation is a conjunction of three claims. First, that even in those dimensions where we are capable of picking up information, there is information that we don’t pick up. Second, that there can be dimensions of information for which we lack the capacity to pick up any information whatsoever. Third, that we don’t know whether the faculties and cognitive capacities we are endowed with process all (...) the information that they pick up. (shrink)

One of the reasons the history of parapsychology and its ancestor psychical research is intriguing is because it addresses a central issue: the boundaries of science. This article provides an overview of the historiography of parapsychology and presents an approach to investigate the Dutch history of parapsychology contributing to the understanding of this central theme. In the first section the historical accounts provided by psychical researchers and parapsychologists themselves are discussed; next those studies of sociologists and historians understanding parapsychology as (...) deviant and even potentially revolutionary are dealt with; third, more contemporary studies are examined whereby enterprises such as parapsychology are understood as central to the culture in which they arose. On the basis of this analysis a new direction in the historiography of the subject is suggested in the fourth section, centred upon the relation between parapsychology and psychology in the Netherlands throughout the 20th century. In the Netherlands not only were pioneering psychologists such as Gerard Heymans (1857–1930) actively involved in experiments into telepathy, the first professor in parapsychology in the world – Wilhelm Tenhaeff (1894–1981) – was appointed in 1953 at Utrecht University and in the 1970s and 1980s parapsychology had its own research laboratory at Utrecht University in the division of psychology. This unique situation in the Netherlands deserves scholarly attention and makes an interesting case to investigate the much-neglected connections between the fields of psychology and parapsychology in the 20th century. The connections between psychology and parapsychology might help us to understand why parapsychology came to be regarded as a pseudoscience. (shrink)
