Words Worth Noting - March 26, 2025

“remember that neither scientists nor laymen learn to see the world piecemeal or item by item. Except when all the conceptual and manipulative categories are prepared in advance – e.g., for the discovery of an additional transuranic element or for catching sight of a new house – both scientists and laymen sort out whole areas together from the flux of experience. The child who transfers the word ‘mama’ from all humans to all females to his mother is not just learning what ‘mama’ means or who his mother is. Simultaneously he is learning some of the differences between males and females as well as something about the ways in which all but one female will behave toward him. His reactions, expectations, and beliefs – indeed comma much of his perceived world – change accordingly.”
