FOUR IDOLS
-Idols of the tribe are certain characteristics that everyone shares. These usually contain the tendency of our senses to deceive us about what is really there, our inclination to wishful thinking, and our hasty generalizing tendencies before a careful investigative work has been done.-Idols of the cave are conceptions or doctrines which vary from person to person and are usually result of preconditioned system of every individual, comprising education, custom, or accidental or contingent experiences.
- Idols of the marketplace are false conceptions which arise from interactions between men, usually through language. The tendency to use language too casually and imprecisely can cause problems in inductive reasoning.
-Idols of the theatre are prejudices from received or traditional philosophical systems. The theories and dogmas by which we are already familiar with can possibly lead us away from investigating for the truth.
