A Report on the Psychological Concepts of Pleasure and Happiness in Mulla Sadra's Philosophy

Happiness or well-being is among the central issue of many psychological considerations. In other words, it can be claimed that the essence of the existence of sciences such as psychology is the pursuit of human happiness and the removal of unhappiness in humans, which has been of great interest to psychologists regarding concepts such as joy, sadness, and peace. Dr. John Schindler believes that: happiness is a quality of the mind that makes the thought enjoy the time. Pleasure in psychology is more born from the "principle of sensual transformation" than a kind of psychological activity, so it can be more accurately considered to indicate the "principle of pleasure/pain." It means that it is a process that avoids the increase of emotional stimulation, whether in the view of psychology such as Freud. Increasing stimulation has no result except pain and suffering. Pleasure is nothing but reducing stimulation (pain). According to the principle of pleasure, sensual activities are nothing but an effort to avoid pain because pain results from increasing the amount of stimuli. On this basis, a happy person has a pleasant life and less pain. Such concepts are also of interest in philosophy, and in the meantime, Islamic philosophy has also expressed definitions and proofs in this regard. As the evolved form of Islamic philosophy, the supreme wisdom of Mullah Sadra has paid particular attention to pleasure and happiness, which we have discussed according to their importance
