It does not have the character of a true disclosure of an external reality.

It is the presence of the form of the sensible thing in the sense faculties. In 'The Theory of Knowledge', we pointed out that sense perception is nothing but a form of conception. Causality and the Objectivity of Sense Perception Were it not for the principle and laws of causality, it would not be possible to demonstrate the objectivity of sense perception, nor any scientific theory or law.įurther, it would not be possible to draw any inference in any field of human knowledge on the basis of any kind of evidence. The following things depend on the principle of causality: (1) demonstration of the objective reality of sense perception (2) all the scientific theories and laws that are based on experimentation and (3) the possibility of inference and its conclusions in any philosophical or scientific field. That is why human beings are always confronted with the question: 'Why.?' This question is raised concerning every existence and every phenomenon of which they are aware, so that if they do not find a specific cause, they believe that there is an unknown cause that produced the event in question. They search for the source of a sound, again in order to know its cause. Thus, such animals instinctively pay attention to the source of motion in order to know its cause. This motive is inborn in human nature.Īlso, is may be present in a number of animals. 808) a human being finds at the heart of his nature a motive that causes him to attempt to explain the things he encounters and to justify the existence of such things by disclosing their causes. It is one of the necessary rational principles for (p. This principle states that for everything there is a cause. The principle of causality is one of the primary propositions known to people in their ordinary lives.
