The ancients and moderns thought about the duality of love and hate. The Greeks formulated myths explaining the emergence of love, philosophers meditated and came up with doctrines that explain this phenomenon, and psychologists and life scientists spoke the word of modern science. The legends of the ancients are not devoid of humor, and the explanations of our moderns are closer to the truth. The meaning that drives people's actions in their lives may be love and hate. They are the secret of the coalition, and the reason for the difference. When a scholar of philosophy and psychology, such as Professor Dr. Ahmed Fouad Al-Ahwani, writes about love and hate, he digs into the actual and true meaning of both words in our living reality. Get to know what motivates you, and what keeps you still like a stone. Get to know love and hate.
