Abstract: Failure Study is the science and technology focusing on success and safety based upon failures and aiming at the future and development from study of the past and history. The philosophical idea of failure study is with universal applicability. Basic principles, philosophical concepts and application of failure study are described from epistemology, contradictions, systematology and methodology. The theory and application of failure study are studied, explored and analyzed, to raise the concept and application of failure study to the height of philosophy, which is an initial attempt to open up a new field. Epistemology of failure study shows that failure is inevitable. It is necessary to establish a correct view on safety and risk management concept, to fully understand important role of security risk management and safety process management. Contradiction analysis in Failure Study considers that it is important to establish a point of view that every coin has two sides and contradictions can be transformed, and to fully understand the leading role of internal cause in transformation process and the importance of all-staff and self safety management. Systematology of failure study believes it is significant to establish the view that system is the starting point and destination of failure analysis, and to fully understand the important role of the hierarchy and the importance of safety management systems. Methodology of failure study indicates that it is crucial to master the system analysis method, the outside-to-inside type of analysis methods and the forward-backward iterative exploration methods.
