Are moral claims epistemically subjective?
Posted: Sun Sep 14, 2025 8:02 pm
John Searle is famous for making the distinction between two different types of objectivity and subjectivity: the ontological type and the epistemological type.
This post will be concerned with whether or not moral statements are epistemologically subjective. But in order to do so, we have to first make it super clear what that term actually means.
Wikipedia seems to be using the exact same concept for the word "subjectivity", so I will quote it here.

The term "epistemic subjectivity" actually refers to an attribute of a claim that satisfies the following two conditions:
1) its truth value is dependent on one or more minds
2) its truth value cannot be established because the claim is open or incomplete
An open statement is a statement that has at least one free variable. The truth value of such a statement is relative, and thus, possibly variable. Its truth value is relative to the values assigned to its free variables. An example would be, "Eating gluten is bad for X" where X is a free variable that ranges over all possible human beings. Its truth value depends on the value of X. If X changes, its truth value may also change.
An incomplete statement is a statement that has a number of crucial details missing that must be filled in before its truth value can be determined. An example would be a statement such as "Eating gluten is bad" where "Bad for whom?" is not implicitly given.
Let's take as an example the following claim:
"Exercise is fun".
What makes this statement a candidate for an epistemologically subjective claim are the following two facts:
1) fun is a mental state, so its truth value depends on one or more minds
2) a thing is always fun to someone
2) the statement does not explicitly state to whom exercise is fun
Contrary to what forum literalists, and other superficial readers, would like to think, the fact that a statement does not explicitly state something does not mean that it does not do so implicitly. As such, "Exercise is fun" is NOT necessarily an epistemological claim.
"Exercise is fun" is an epistemological claim if and only if there is no way to determine its truth value, e.g. if "to whom exercise is fun" is a free variable or not specified at all.
I am afraid that this makes most, if not all, moral claims epistemologically objective.

This definition is far from being clear. In fact, if you ask me, it's quite terrible. So we can't stop here.Wikipedia wrote:Something is subjective if it is dependent on minds (such as biases, perception, emotions, opinions, imaginary objects, or conscious experiences).[1] If a claim is true exclusively when considering the claim from the viewpoint of a sentient being, it is subjectively true. For example, one person may consider the weather to be pleasantly warm, and another person may consider the same weather to be too hot; both views are subjective.
