Comparing two traditions is so important in those each of them has tried to solve some philosophical problems.• Causality is an important subject in philosophy. • Causality in the view of Berkley: • Before explaining causality, he tried to explain reality and existence.• The external existence of objects means their being perceived.• Causality isn’t an objective matter.• What has been named cause and effect is now a signifier and signified. For all the relations established among objects, Berkley is among the first ones to attach a subjective aspect to the causality• The analysis of causality is possible only through an awareness of the way God acts to present perceptions.• As a result, although in Berkley’s attitude causality transforms into significance in what we call the external object and turns into a subjective issue, he accepts that real causality exists between man and his perception.
