Problem:
Except in the case of David Hume's Moral Sense Theory (AKA Emotivism) and other forms of moral relativism, the conscience is not considered to be the foundation of an ethical system or what determines what is morally right and wrong. Instead, the conscience is considered only a part of each normative ethical systems (e.g., virtue ethics, deontology, etc.). In these normative systems, the conscience is not what makes things morally right or wrong but an internal source of knowledge about which particular things are morally right and wrong. For example, a deontologist might know that stealing is wrong based on what their conscience tells them but hold that stealing is an intrinsically morally wrong action and is wrong even if our conscience mistakenly tells us it is not. Given the above statement, do you think conscience is the best guide or indicator of moral truth? Why or why not? Does the fact some people seem to lack a conscience and moral sense similar to most others (as in the case of psychopaths and sociopaths) prove that morality is subjective? Why or why not? Based on your previous answer, what are the real-world consequences of morality being either objective or subjective?
