这种说法不算错误,但并不严谨。具体语源学的流变,我不是希腊语专家,所以没法去考察。但这两个词的直接关系,你看看希腊语原文就能看出来。国内外哲学界普遍认为伦理和道德均来源于古希腊语中的“风俗、习惯”一词
Virtue, then, is of two kinds: that of the intellect and that of character. Intellectual virtue owes its origin and development mainly to teaching, for which reason its attainment requires experience and time; virtue of character (ēthos) is a result of habituation (ethos), for which reason it has acquired its name through a small variation on `ethos'. From this it is clear that none of the virtues of character arises in us by nature.
一.ἦθος和ἔθος, 两者是同源的,同出自PIE的词根?*sedʱh1-, 意思是sich selbst als/für, zu etw. bestimmen.实际上ηθος是一个含义非常丰富的词。可以说,εθος有的意思它也有(风俗、习惯),但它还包括更多的含义(品格)。
