Samuel Johnson (of Boswell fame) said about writing, âwhatever is written without effort is in general read without pleasureâ and âthe unexamined word is not worth reading.â However, even the most thoughtfully written text is unlikely to be described as a good read. This book is not an exhaustive review. Rather it is an uneven selection of examples whose interplay across disciplines hopefully illuminates what drives the practice of forest production, wood processing and consumer preferences. The choice of material is arbitrary reflecting personal biases. It is a summary of material presented to students at the NZ School of Forestry at the University of Canterbury. This book takes liberties with other peoplesâ ideas, weaving them into fresh themes that are at best a work in progress. The philosopher Francis Bacon argued that âscience is a debate in progress not a body of knowledgeâ and also âtruth emerges more readily from error than confusionâ. We have taken the position that it is preferable to venture a reasoned opinion and be proved wrong than to waffle; so donât swallow every sentence â âdoubt everythingâ. The readerâs task is to unravel the conceits of generalizing and the risks of particularizing.
