There are only three integral views of the world: the religious, the materialistic, and the Islamic. They reflect three elemental possibilities (conscience, nature, and man), each of them manifesting itself as Christianity, materialism, and Islam. All variety of ideologies, philosophies, and teachings from the oldest time up to now can be reduced to one of these three basic world views. The first takes as its starting point the existence of the spirit, the second the existence of matter, and the third the simultaneous existence of spirit and matter. If only matter exists, materialism would be the only consequent philosophy. On the contrary, if the spirit exists then man also exists, and man's life would be senseless without a kind of religion and morality. Islam is the name for the unity of spirit and matter, the highest form of which is man himself. The human life is complete only if it includes both the physical and the spiritual desires of the human being. All man's failures are either because of the religious denial of man's biological needs of the materialistic denial of man's spiritual desires.
