Question

In moral considerations and judgment, only one's feelings matter in the discipline of ethics since it only involves, by definition, an expression one's own subjective opinion.

Answer 1

Answer:    This is true and concerns subjectivism

Explanation:  Subjectivism implies that moral reasoning and judgement come from the subjective feeling of individuals, and as such it is contrary to the so-called objective judgement of what moral values ​​are, i.e, objectivism. Subjectivists, therefore, unlike objectivists, argue that judging ethical values ​​cannot exist independently of individuals' feelings in the given particular  circumstances, particular time, and all others, current opinion, education, level of knowledge of particular theme etc. Subjectivism rejects objective moral values ​​as an illusion. So the sense of morality and moral judgement comes from individual feelings.
