The diverse number of N-space theories and the unrestrained growth of the number of spaces within the multiple space models has incurred general skepticism about the new search space variants within the search space paradigm of psychology. I argue that any N-space theory is computationally equivalent to a single space model. Nevertheless, the N-space theories may explain the systematic behavior of human problem solving better than the original one search space theory by identifying relationships between the tasks that occur in (...) problem solving. These tasks are independent of the particular process and may not be explicitly represented by the problem solver. N-space theorists seem to overlook their own reason for distinguishing N-space theories from single space models, namely the presupposition that these tasks must have a unified, underlying search space architecture. This assumption is ill-founded and may implement a procedural restraint that could impede psychological research. (shrink)

The philosophical implications of food are absent from most philosophers’ repertoires. Thus, it is not surprising that most people are unaware of how various aspects of food can affect philosophy, and how philosophy can influence our ideas about food. Elizabeth Telfer’s book, Food for Thought, excellently illuminates some of the relationships philosophy has with food. Nonetheless, for those with a strong appetite for the philosophy of food, her book may not sate your philosophic palate.
