Quote by Lawrence Kohlberg
"The highest moral achievement is acting justly even when it costs us something."
More from Lawrence Kohlberg
"The highest stage of moral development is when we act morally not because we fear punishment or seek reward, but because we believe it is right."
"Moral development is not something that happens to us, but something we actively construct through our experiences and reflections."
"We do not live in a moral vacuum; our choices are shaped by the society we inhabit and the values we have internalized."
"Justice is the highest virtue because it encompasses all other moral principles."
