ABSTRACT
This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book suggests that almost any accident can be said to be due to an error by someone and the use of the phrase discourages constructive thinking about the action needed to prevent it happening again. Wrigglesworth wrote that accidental death is now the only source of morbidity for which explanations that are essentially non-rational are still socially acceptable. Biologists have abandoned the idea of protoplasm as the physical basis of life, something which permeates inanimate structures and gives them vitality. Perhaps the time has come when the concept of human error ought to go the way of phlogiston, the ether and protoplasm. According to Dewey, intellectual progress usually occurs through shear abandonment of questions together with both of the alternatives they assume an abandonment that results from their decreasing vitality.
