That’s quite possibly true. (Look up “conscious evolution.” Although that is not endorsed by the Church–just some crazy liberal American nuns.)
I looked at the Wikipedia article. It didn’t really tell me very much, but I agree it sounds a bit strange on the surface of it. I guess it depends on what they mean by words such as evolution and species.
There are subjective aspects to valuing; I also do not deny that “value” is to a large extent a family resemblance concept (ie. that we could not subsume our use of the term under a single set of necessary and sufficient conditions). It doesn’t really follow that no sense of the term “value” can be objective. But I will get to that below.
Well, I don’t know what objective would mean in this context. It is not that I deny it. I simply don’t know what it means. For instance, if God says humans are the most valuable creature on our planet, how does this make it objectively true? You could say it is true by definition, but it would only be true to those who accept the definition, and the reasons for it. One would assume the devil disagrees. God, being omnipotent, can of course sanction the devil for not accepting his authority, but I don’t see what power has to do with objectivity.
I agree with this to a large extent, in that a knife is an artifact, so its “purposes” and “ends” are functions of the intentions of the user.
Ok.
I have not suggested that by evaluating anything, we are attributing value to it. Evaluation can be partly subjective. A-T concedes this, because the difference of any transcendental (ie. things that are convertible with being, like goodness, truth, arguably beauty) with being is a difference of sense but not of reference (so we refer to the same reality). When I evaluate a thing, I am referring to the aspect of its being qua desirable.
Well, I doubt that there is anything that is desirable in and of itself. Desirable to whom? A human, heterosexual male might find a certain young woman desirable. I am quite sure a cat, frog, leopard, bird, or some other animal will look at her in entirely different ways. Meaning that desirability to some extent is a function of the mind of the perceiver. It also changes over time as physical attributes change, context changes, etc. The first iPhone that was launched was viewed as highly desirable a few years back. Now, not so much. Also, no composite seems to last for ever. At least not in my experience, and so as something decomposes, it becomes less desirable.
Cat is a conceptual label; it does not follow that our usage does not correspond to any formal principle of unity in res. I would argue that it does. (Whether two cats are the same is irrelevant; of course any two distinct cats are non-identical, even if they are “identical” twins.)
Of course. We can both recognize a cat if we see one. But the concept of a cat is an abstraction we have created due to the limitations of the human mind, and for purposes of communication. We have derived the concept from observing several living beings. It is descriptive, not prescriptive. The value judgement of what is or is not a good cat is not determined solely by looking at this abstraction.
Note that the dispute over whether value can be objective then hinges on whether or not one can accept essentialism. That’s another debate, but it’s a position that is far from implausible. (And essentialism is a view that has seen a revival in contemporary philosophy in the last few decades.)
Yes. You hit the nail right on the head. Essentialism is the issue.
If the change is sufficiently large, then you no longer have a cat on your hands. I’d suggest that if what are currently cats evolved to have three legs, then they would be a new species with a new corresponding set of ends and purposes rooted in their form.
Well, you could say that, but species designation is a conceptual label, much like knife or table. One could, if one were so inclined, refer to all sentient beings on earth as one species, such as earthling. There are practical reasons why we divide animals into species, but the divisions are human conventions and could easily be different than what they are without violating principles of logic and reason.
Such theists are I think being intemperate. Formally, “Humans have inherent value” implies that “God exists” (or one could make that argument). But the former can be recognized without one having recognized the latter. That is why it is possible for there to be, for example, atheists of good will, and it is also why it is possible for atheists to sin knowingly and willingly despite not knowing that God exists.
Well, I think it is quite possible to be a person of good will, who greatly values humans (and other sentient beings) without thinking that value is contingent on some sort of internal essence within certain animals. This kind of thinking can lead to all kinds of suffering. Slavery, for instance, is usually based on dehumanization. Dehumanization is based on essentialism, because the dehumanizer thinks that there are animals that look just like humans, but they lack the essence of what makes someone truly human and therefore what gives them value (people who kept slaves argued that their slaves lacked souls, for instance, and hence it was acceptable to treat them as less-than-human animals). Some argue that fetuses lack this elusive essence, and so it is ok to kill them, others argue that criminals no longer are human, that their actions have destroyed their human essence, and so they may be “monsters” or “pond scum” that we not only could, but ought to kill.
What we are discussing are not merely abstract philosophical ideas. They have real world consequences.
