Yochanan ben Zakkai — What Is the Straight Path?
Rabban Yochanan ben Zakkai's question to his disciples — 'What is the good path to which a person should cleave?' — and their answers form a complete ethics of character.
Rabban Yochanan ben Zakkai asked his five disciples: 'What is the good path to which a person should cleave?' Rabbi Eliezer said: a good eye (generosity of spirit). Rabbi Joshua: a good friend. Rabbi Yose: a good neighbor. Rabbi Shimon: foresight (seeing consequences). Rabbi Elazar: a good heart. Yochanan accepted Elazar's answer — 'a good heart' — as encompassing all others, since a person with a genuinely good heart will naturally have a good eye, be a good friend and neighbor, and act with foresight. This teaching operates on multiple levels: it is a ranking of character virtues; it demonstrates the Talmudic method of gathering diverse perspectives; and it shows that the master's role is not to impose a single answer but to invite the disciples to find their own, then evaluate them together. The 'good heart' (lev tov) as the root of all virtues anticipates Aristotle's concept of phronesis (practical wisdom) — the general virtue that enables all specific virtues.
A good heart — for the good heart includes all the others.
Character psychologist Martin Seligman's concept of 'signature strengths' — the core virtues that, when exercised, enable all other virtues to flourish — parallels the Talmudic teaching that a good heart is the root virtue from which all other ethical qualities naturally grow.
