Our viewpoint on nature is our phenomenological perspective, our reality, our ontology. But we are not only of an existential world. We also act within an arena of moral judgment and responsibility. Our ethical system itself comprises a perspective, one providing us with our shoulds and oughts. We should not lie.
Citizens ought to participate in government.
The rivers should be unpolluted. If we judge that we should be held morally responsible for our acts, we are constrained from accepting absolute determinism. If we believe that all meaningful propositions should be intersubjectively verifiable, confirmable, or falsifiable, then the introspective self and will cannot be meaningful. And if we feel that punishment should only function to deter immorality and illegality, then determinism is possible. The ontological and ethical restraints that comprise a person's preferred beliefs and values are like fields of balanced experiences, emotions, and thoughts.
