The Darwin-Hecker hypothesis, viz. that laughter induced by tickling and humor share common underlying mechanisms, is so-called in part because of a quotation attributed to Ewald Hecker. However, a German counterpart of the quotation does not appear in the location cited. Some textual sleuthing is undertaken to find out what Hecker actually wrote and where he wrote it.

Abstract. This paper illustrates how philosophy and science may converge and inform one another. I begin with a brief rehearsal of John Morreall’s “formulaic” theory of laughter, that laughter results from a pleasant psychological shift, and of my previously published criticisms and counterproposal that laughter results from titillation (where “titillation” is a semitechnical term). I defend my own position against charges that it is trivial, circular, or vacuous (charges that, if correct, would apply equally to Morreall’s position), showing that these (...) charges are misguided or premature. Then I indicate how my position is reflected in and might be given empirical content by a hypothesis that is already under preliminary experimental investigation in psychology, namely the Darwin-Hecker hypothesis, and also how my position is in harmony with recent work in psychology alleging the discovery of evolutionary antecedents of human laughter in rats.

Recently, there has been a burgeoning of interest in the relationship between Schopenhauer's philosophy and Indian thought.1 One major reason for this trend is the growing conviction among scholars that a careful understanding of Schopenhauer's complex—and evolving—engagement with Indian thought can help illuminate crucial aspects of Schopenhauer's own philosophy.2 The late nineteenth-century German scholars Paul Deussen and Max Hecker are widely acknowledged to be the pioneers in the field of Schopenhauer's relation to Indian thought. Deussen, thoroughly trained in both (...) indology and Western philosophy, was the first to bring Schopenhauer's philosophy into dialogue with Indian thought... (shrink)
