Prabhupāda: At the present moment there is all over the world—we are touring all over the world—it is very hard to find out ideal class of men. That is the defect. In the Vedic culture the ideal class of men were the brāhmaṇas. Their qualification was: truthful; self-controlled, mind and the senses; and then tolerant; very simple life; full of knowledge, practical application of knowledge in life; and full faith in God. These are ideal character. But such men are not available at the present moment. So therefore the social idealism is defective. Just like in your body there are four divisions: the head, the arm, the belly and the leg. If the head is spoiled, then you are a madman. In spite of possessing hands and bellies and legs, you cannot work properly. So at the present moment the heads are spoiled. Therefore the whole world is in chaotic condition. People advanced in education, still they are inimical, one man to another. If you are passing on in the street, the gentleman's house there is a signboard, "Beware of the dogs. Don't come in," because he cannot believe anyone. You go to the airport, any high-class standard man, they search out the pocket. So nobody is believable. This is the result of modern education. You cannot find out an ideal character man.
Richard Webster: Is this due to machines, do you think, to the prevalence of machines?
Prabhupāda: No. Yes. It is due to third-class, fourth-class men. There is no first-class men. The brāhmaṇas are considered to be first-class men, the kṣatriyas are considered to be second-class men, and the vaiśyas, they are third-class men, and rest, all fourth class and fifth class. So at the present moment there is third class, some, and all fourth class and fifth class. There is no first-class and second-class men. So unless they are, at least some of them are first-class men, ideal, the human society is doomed. It cannot be peaceful. Full of śūdras, fourth-class men. Our Kṛṣṇa consciousness movement is meant for creating some first-class men. This is our ideal. Therefore we forbid them not to take meat, not to have illicit sex, not to . . . because these things are accepted by the fourth-class, fifth-class men—unrestricted sex life, meat-eating, intoxication, gambling. They are not to be indulged by the first-class, second-class men, even third class. It begins from the fourth-class men, fourth class, fifth class. So if one remains to the category of the fourth-class, fifth-class man, how he can be trained up as first-class man? Therefore these things are prohibited, because our aim is to create some first-class men.
