But I do pose the manner in which I construe the meaning of dasein above as revolving around ethics, morality and the law.
In judging George’s action there are facts that can be demonstrated/established. Objective truths embedded in his life predisposing him to shoot the dog.
Mitigating circumstances they might be called if it were ever to become a matter of the law.
Dasein as I understand it is largely moot here. There are facts about “I” which are not really open to dispute. Where was “I” born"? When was “I” born? What are “I’s” genetic/biological components? Who were part of “I’s” family? “I’s” community? What was “I” indoctrinated to believe about particular moral and political issues as a child? What was “I” indoctrinated to believe about God and religion as a child. These are facts that may or may not be conclusively established. Facts that objectively are true for all of us. Why? Because they are in fact true.
It’s just that even in the either/or world only an omniscient God would have access to all of the facts. Facts going all the way back to an understanding of existence itself.
But human interactions with dogs varies down through the ages. And they produce conflicting cultural/individual narratives. For some dogs are part of their diet, for others they are raised to fight other dogs; or, for others still, they are trained to be performers or drug detectors or killers.
The dasein part [as I understand it] revolves around our personal reactions to these behaviors — behaviors construed to be either moral or immoral. As then construed to be bahaviors that ought or ought not to be proscribed.
In other words, philosophers/ethicists do not appear [to me] to have at their disposal the tools necessary to resolve these conflicting narratives/values/behaviors.
How are rational men and women obligated to treat dogs?
And the crucial factor embedded in the determinism debate revolves around establishing the extent to which all human behaviors are only ever as they could have been.
No less so in human beings than as in dogs. As in termites. It’s just that our own species has acquired the illusion that “I” chooses these things with at least some measure of actual autonomy.
