Foundations of clinical praxiology part II: Categorical and conjectural diagnoses

  • Kazem Sadegh-Zadeh


The concepts of categorical diagnosis and conjectural diagnosis are introduced. It is argued that in diagnostic reasoning conjectural diagnosis plays a more important role than categorical diagnosis. Attention is called to the inevitable vagueness of clinical language and to the suitability of epistemic logic and fuzzy logic for diagnostic reasoning.

Key words

Categorical diagnosis Conjectural diagnosis Epistemic attitudes Epistemic kinematics Epistemic logic Approximate clinical reasoning
