Reality exists in the empirical world and not in the methods used to study that world; it is to be discovered in the examination of that world. … Methods are mere instruments designed to identify and analyse the obdurate character of the empirical world, and as such their value exists only in their suitability in enabling this task to be done. In this fundamental sense the procedures employed in each part of the act of scientific enquiry should and must be assessed in terms of whether they respect the nature of the empirical world under study – whether what they signify or imply to be the nature of the empirical world is actually the case
