One of the essential pillars of Islam is the care for man’s human aspects, and the most important elements of which are the cognitive and emotional sides. And these two sides represent the cornerstone of the behavioral aspect. The cognitive dimension develops beliefs, and the more your cognitive dimension is based on mental proofs, the more sober man’s beliefs shall be. The same is said about the emotional aspect represented by morals, that whenever the emotional aspect is inspired by human values and principles that Islam has declared, morals shall be high and shall not be affected by alien moralities. Also, with regard to the behavioral aspect, whenever a person relies on demonstrative reason and the values and principles stipulated by the Sharia, he shall be more sober-minded, preserving the rights of individuals and society. As for cognitive, emotional, and behavioral aspects according to humanists, they depend on material matters that lead to relative knowledge. In the cognitive aspect, empirical reason is adopted to lead to relative knowledge. In the emotional aspect; humanists see that values and principles in societies are at one level and there is no difference between them; as they differ according to different cultures of societies. And as for the behavioral aspect -because of cognitive and emotional aspects- it is natural to see phenomena that contradict human nature; therefore, man behaves beastly and lustfully because of the exclusion of religion and reason in daily life.
