A
Talmid Chakham must avoid six acts: to go abroad in perfumed garments; to walk alone at night; to wear shabby shoes; to converse with a woman while on the street (even if she is his wife); to sit in the society of an ignoramus; to be the last to enter the
beth midrash. With regard to association with an ignoramus, the Talmud says: "The
Talmid Chakham is first likened by the ignoramus to a vase of gold; if he converses with him, he is looked on as a vase of silver; and if he accepts a service from him, he is regarded as a vase of earth." Among the privileges of the
Talmid Chakham is the right of declining to present himself as a witness in suits concerning money transactions before a judge who is his inferior in knowledge. The
Talmid Chakham was expected to be familiar with all branches of Torah study and even all branches of general human learning. "He who understands
astronomy", says
Yochanan bar Nafcha, "and does not pursue the study of it, of that man, it is written: 'But they regard not the work of the Lord, neither consider the operation of His hands'" (
Isaiah). Rabbi Yochanan also says that only someone able to answer all Halakhic questions, even those which deal only with the insignificant treatise
Kallah, is a
Talmid Chakham worthy to be appointed leader of a community. In accordance with this view, some later rabbinical authorities assert that in modern times no one deserves to be called by this epithet. The principles with which the
Talmid Chakham must live are enumerated in the first chapter of the work
Derekh Eretz Zutta, opening with the following sentence: "The way of the wise is to be modest, humble, alert, and intelligent; to endure injustice; to make himself beloved of men; to be gracious in his interactions, even with subordinates; to avoid wrong-doing; to judge each man according to his deeds; to act according to the motto, 'I take no pleasure in the good things of this world, seeing that life here below is not my portion.' Wrapped in his mantle, he sits at the feet of the wise; no one can detect anything unseemly in him; he puts relevant questions, and gives suitable answers." ==Social position==
