These same Bauddhas discuss the highest end of man from four standpoints. Celebrated under the designations of Mādhyamika, Yogācāra, Sautrāntika, and Vaibhāshika, these Buddhists adopt respectively the doctrines of a universal void (nihilism), an external void (subjective idealism), the inferribility of external objects (representationism), and the perceptibility of external objects (presentationism).[3] Though the venerated Buddha be the only one teacher (his disciples) are fourfold in consequence of this diversity of views; just as when one has said, "The sun has set," the adulterer, the thief, the divinity student, and others understand that it is time to set about their assignations, their theft, their religious duties, and so forth, according to their several inclinations.
