The Nazis were wrong!

Over at Well that was Daft Nasher lays out his position on objective and subjective truths. I have a different take on this subject to him and one critique of his post that may make him rethink things a little.

First, let’s get clear on the distinction between objective and subjective. Following John Searle I’ll distinguish between two types of questions: metaphysical and epistemological. Metaphysical questions concern “what exists?” Something exists objectively if its existence doesn’t depend on it being experienced. For example, the Earth exists whether or not there is someone here to experience it. On the other hand, subjective existence depends on being experienced. The feeling of a stubbed toe or the aroma of a nice Sauvignon Blanc are metaphysically subjective and their existence depends on me experiencing them. The experience is unique to me, you could never find out the way stubbing my toe felt to me.

However, Nasher is more concerned with epistemological questions. These are questions regarding “what is true?” Epistemologically objective statements can be true or false but the methods used to determine their truth value have to be publicly available and generally agreed upon. By ‘publicly available’ I mean not reliant on personal subjective experience and ‘generally agreed upon’ means that reasonable people, when presented with the same evidence, would come to the same conclusion. To take Nasher’s example:

“Some things are absolutely, objectively true. That the Earth is round is an example of this kind of truth.”

This is indeed an objective statement. We can take a publicly available observation – departing ships sink below the horizon – and draw the reasonable conclusion that the Earth is round. Epistemologically subjective statements are those whose truth value is determined by metaphysically subjective evidence. If I was to say “apricots taste better than strawberries” the primary evidence in determining the truth of that statement would be how different fruits taste to me. Someone else who has different subjective experiences of taste could reasonably disagree with my statement.
Nasher proposes a novel test do determine whether a truth statement is objective or subjective:

“Did the Nazis themselves think they were justified [in the systematic extermination of six million Jews]? If the answer is "yes", if even a single Nazi considered the holocaust justified, then the answer to this moral question is subjective. In fact, all it takes is the capacity for someone to consider it justified and it becomes subjective.”

But is this test sufficient? What if we change the topic and consider a flat-Earther? Surely there is a single flat-Earther who considers their position on the shape of the Earth to be justified, or - if not - we can at least agree there is the capacity for someone to consider the flat Earth position justified. According to Nasher’s test this makes the issue of the planet’s shape subjective, but earlier we agreed that this was an objective question. I would submit to Nasher that his central test for subjectivity leads to outcomes that he would reject.

We could modify the subjectivity test slightly to avoid my objection. If we said that no reasonable person could find flat-Earth justified then we have a second criteria that would eliminate the problem. But now we have to apply the new criteria to the moral question, could a reasonable person find the Nazi holocaust justifiable? Nasher seems to think not:

“Obviously, your answer is "no". I share your sentiments. I consider the Holocaust to be one of the worst crimes committed in human history. If you do not feel the same way, I invite you to jump off a skyscraper and rid the rest of the world of your barbaric views.”

I agree. Someone who thinks the holocaust was justified, even if they are Nazi, is either lacking certain information or is just not thinking in a reasonable way - a "barbarian".

Since morality is based on certain objective facts about the world and a need for clear and rational thinking, it seems morality is much closer to the realm of epistemological objectivism than subjectivism. Hence why am a moral objectivist and can confidently say that the Nazis were wrong!
