I have been thinking recently about what might be four ethical ideas that I wish were taken more seriously, or taken seriously among a wider group of people, and these are the four I came up with:
(1) Some things that are morally permissible are nonetheless morally risky.
(2) Enduring difficulty is itself a human excellence.
(3) We should restrain ourselves even when dealing with good and innocent pleasures.
(4) Exchanges should be done in such a way that all parties to the exchange benefit in some way.
The sharp eye might note the connection to the cardinal virtues. What are some ethical ideas that you think should be taken more seriously?
