"Plato said: 'A true human is he whose 'lingual self' is stronger than the rest of his other types of selves, because if lustfulness is excessive, a person becomes an animal. If a person releases his Hawā, lives an unrestrictive life, then he becomes displaced from his centre, hence he will become worse than an animal, because that is actually the nature of animals, but, in his case, he has contradicted his [humanly] nature. And when the anger capacity is excessive, humans' traits become as that of wild and beastly animals. Hence, one should tame his inner self by opposing lustfulness, controlling anger and following the lingual capacity, so as he may become like the angels and avoid worshipping lust and anger.'"
