These answers always lead me to more questions for which I would like rational answers. For example, why be virtuous? What is in it for me?
I don't buy the the argument from effect such as the one below. There are a lot of people who benefit from harming others without repercussions. Take for example politicians or wall street bankers.
"If you initiate the use of force against others, you give them a reason to harm you."
"It takes more effort than NOT initiating the use of force and incurs greater risk."
Don't buy this either. A lot of things that take more effort are good for you in the long term such as exercise.
"because that is what makes us virtuous, and that leads to happiness. "
This statement is not a logical argument. But I am curious whether this is even empirically true. Is there data that proves this? Are there exceptions?
