Objective v. Subjective
Subjectivism
If I believe X is morally right, then (for me) it is morally right. What makes it right? The fact that I believe it is. If you disagree with me, neither one of us is correct or incorrect. We just have different (perhaps competing) moral values. There is no "true" morality against which to judge either of our opinions.
it's objective
If a claim must be either true or false (even if we're not sure which), and, if, in the case of disagreement, at least 1 person must be mistaken
Objective moral theories
claim that what is morally right or wrong is universally so, independently of our own opinions (i.e., applicable to all people at all times).
Objective
claims appeal to "facts," and are independent of our opinions/preferences.
Subjective
claims appeal to "opinions," and are often merely expressions of personal preference
The 2 main types of subjective theories
cultural relativism and subjectivism.
Subjective moral theories
do not claim believe that what is right and wrong to all people at all times.
