Book 4 turns from the general theory of virtue to particular excellences: wealth, honor, anger, social life, and truth-telling. Aristotle begins with liberality, the mean in giving and taking money. The liberal person gives to the right people, in the right amounts, for noble reasons, and takes only from proper sources without clinging to wealth as if money were the point of living. Stinginess hoards. Prodigality wastes. Some people labeled prodigal are really self-indulgent spenders chasing pleasure through outlay; true prodigality ruins a life through careless spending that leaves nothing for better uses. Liberality is not warmth of feeling alone. It is skill at matching gift, recipient, and occasion, and it includes knowing when not to take as much as knowing when to give. Wealth is an instrument; character shows in how the instrument is aimed.
Magnificence is liberality scaled up. It fits large expenditure to great occasions: public sacrifices, civic projects, weddings, hosting guests. Scale is relative to the agent and the situation. A poor person cannot be magnificent without looking foolish, because the outlay would crush the means that should support it. The magnificent spender aims at beauty and honor rather than cheap display, more like an artist shaping a public work than a show-off buying applause. Vulgar spenders miss the mark by spending wrongly for attention, turning a festival into an advertisement for themselves. Niggardly people spoil great results by pinching over trifles that should never have governed the design. Aristotle's point is practical: public money and private wealth both need taste, proportion, and a reason larger than vanity.
Pride, or magnanimity, concerns great honor. The proud person rightly thinks himself worthy of great things because he is worthy. The vain person overclaims and needs mirrors more than merit. The unduly humble underclaims and thereby wrongs both desert and truth, shrinking from responsibilities that fit his powers. The great-souled person is measured in praise and blame, slow to petty danger, open-handed with help, reluctant to depend on others, and candid because truth matters more than popularity. Small honors do not intoxicate him; great ones do not make him soft. He remembers benefits he has given more readily than favors he has received, not from coldness but from an unwillingness to live as a debtor to trifles.
Honor also has a quieter middle path without a familiar everyday name. One extreme is the ambitious chase after recognition from the wrong sources and for the wrong acts. The other is the unambitious refusal of honor even when it is deserved. Between them sits proper regard for reputation as one good among others, not the only scoreboard by which a life is tallied. Aristotle refuses both the fame addict and the person who treats indifference to esteem as a virtue in itself. Reputation matters, but only as a signal that can be true or false about what you have actually done.
Good temper is the mean about anger: being angry at the right things, toward the right people, in the right way, and for the right time. The deficient person is spiritless and fails to defend what should be defended, mistaking numbness for peace. The excessive person is hot-tempered, sulky, or vindictive, carrying yesterday's slight into tomorrow's conversation until every room becomes a courtroom. Aristotle admits exact lines are hard to draw in the heat of feeling, yet the middle state remains clearly praiseworthy because it keeps judgment from being either numb or hostage to rage. Anger can serve justice; unmanaged, it only multiplies injury. The test is not whether you feel heat, but whether the heat tracks a real offense and stops when the work is done.
In social life, friendliness is not mere affection. It is hitting the mark in pleasure and pain with companions: neither the obsequious yes-man nor the churl who opposes everything, nor the flatterer who charms for gain. The truthful person calls things what they are about himself. The boaster claims what he lacks. The mock-modest person disclaims what he has, fishing for contradiction. Understatement can be attractive; boastfulness aimed at money is especially ugly because it turns speech into a sales pitch. Leisure matters too. Ready-witted tact knows how to jest and listen as a well-bred person should, keeping play from becoming cruelty. The buffoon sacrifices everything for a laugh. The boor cannot take or make a joke without spoiling the room.
Finally, shame is not a virtue. It is more like a feeling, fitting mainly for youth who still need restraint. The fully good person will not do base actions voluntarily and therefore does not rely on shame as a standing excellence. Book 4's catalog ends by preparing the turn to justice: after private calibration of money, honor, anger, and speech, Aristotle asks what fairness requires when we deal with others as members of a shared life.
