What are the likely benefits of engaging in ethical actions?
There are at least two types of benefits of engaging in ethical actions. One type of benefit is pragmatic and tangible, the other is more psychological or spiritual.
Psychologically or spiritually, if you engage in ethical actions, you are likely to feel better about yourself. You will not feel a guilty conscience over your behaviors. You will be able to feel proud of yourself and your conduct. This is certainly a real benefit.
There are other benefits that are more tangible. For example, ethical conduct is likely to make other people trust you more. If you get a reputation for acting ethically, you will probably be more likely to impress people and make them want to help you. A teacher might recommend you for a scholarship. A businessperson might be more likely to want you to work for them. These sorts of more tangible benefits can also come from ethical behavior.
