In a previous paper, I argued that expert nursing intuition is a form of what James J. Gibson termed ‘direct perception’ and, as such, is information‐based and can be accepted as part of nursing science. In this paper, I explore the philosophical basis for these claims. I begin by describing analogous problems in philosophy and psychology related to how we know the world. After describing the various solutions proposed and the problems they engender, I summarize Gibson’s theoretical solution together with (...) some of the supporting empirical evidence, but emphasizing the ecological realism on which it relies. I then use these insights to reconsider nursing intuition and the implications for its further exploration. (shrink)
