compassion and also good-natured agreeableness are not true virtues, in accordance to Kant's view. The only aspect that makes a human truly virtuous is to behave in accordance with moral principles. Kant presents an example for more clarification; suppose that you come across a needy person in the street; if your sympathy leads you to help that person, your response does not illustrate your virtue. In this example, since you do not afford helping all needy ones, you have behaved unjustly, and it is out of the domain of principles and true virtue. True virtue is the quality of raising the feeling of humanity's beauty and dignity to a principle. When a person acts in accordance with this principle, regardless of inclination, that person is truly and sublimely virtuous. Kant applies the approach of four temperaments to distinguish truly virtuous people. According to Kant, among all people with diverse temperaments, a person with melancholy frame of mind is the most virtuous whose thoughts, words and deeds are one of principles. "A profound feeling for the beauty and dignity of human nature and a firmness and determination of the mind to refer all one's actions to this as to a universal ground is earnest, and does not at all join with a changeable gaiety nor with the inconstancy of a frivolous person." With this observation, Kant will attempt to fit the various feelings of the beautiful and sublime, and the resulting moral characters, into Galen's rigid arrangement of the four humours or human temperaments: melancholic, sanguine, choleric, and phlegmatic. Kant asserted that the human temperaments or dispositions are fixed and separate characters. An individual who has one frame of mind has no feeling or sense for the finer feelings that occur in a person of another temperament. A person who has a constitution that is melancholic will have a predominating feeling for the sublime. That person may possess genuine virtue based on the principle that humanity has beauty and worth. One who has a sanguine nature will mostly have a feeling for the beautiful. This results in an "adoptive" virtue that rests on goodheartedness. This person's compassion and sympathy depend on the impression of the moment. A choleric human will have a feeling for the splendid or showy sublime. As a result, this person will possess an apparent virtue. Kant calls it "a gloss of virtue." This includes a sense of
