This book tries to answer a variety of questions about how 'craft' is created and what influences writing, whether it is the author's own beliefs, his social or economic context, or the many 'environmental' factors that surround the author and of which he is not even aware, these processes are even internal to the author of the work.The writing of this book has been greatly influenced by university professors whose interest in epistemology is very evident and has influenced me as well.
