Diagnosis is the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different
disciplines, with variations in the use of
logic
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the science of deductively valid inferences or of logical truths. It is a formal science investigating how conclusions follow from premise ...
