The final chapters deal with knowledge from the point of view of the individual reader, listener, viewer or consumer, including the problem of the reliability of knowledge discussed so vigorously in the seventeenth century. One of the most original features of this book is its discussion of knowledges in the plural. It centres on printed knowledge, especially academic knowledge, but it treats the history of the knowledge 'explosion' which followed the invention of printing and the discovery of the world beyond Europe as a process of exchange or negotiation between different knowledges, such as male and female, theoretical and practical, high-status and low-status, and European and non-European.
