Trial & Error & The Idea of Progress

This book is an analysis of progress – its meaning, its constituent elements, the conditions that favour it, and the methods people use to achieve it. Its central theme is that progress implies a closer approach to nominated goals; there must be a target to make progress towards. Alternative attempts to achieve progress are tested against each other, and new attempts are tested against old ones. The ones which prove better than their rivals at achieving progress towards chosen goals are retained, and inferior alternatives are discarded.
