Our moral values emerge from biological systems, and ethical norms vary widely across space and time - this is simply an observable fact. These values are shaped by experience, existing within a range of possible options that have both variation and limits.

When discussing human affairs, while we cannot offer mathematical proof, we can observe patterns in how ethical norms develop and evolve. The notion that moral values can range indefinitely is incoherent, as it incorrectly assumes that morality is purely a cultural construct. Consider how people acquire culture: not through instantaneous transmission, but through observing a limited set of behaviors and actions and constructing in our minds the set of attitudes and beliefs that constitutes culture.

This process parallels how we learn language, develop visual systems, or construct scientific theories.

Our DNA provides fixed constraints that guide the development of these universal moral structures while allowing for certain degrees of variation. The assumption that moral values are purely cultural reflections oversimplifies a complex biological and social process.

What can be said about developing moral character is that it is critical to foster tolerance for variation while maintaining opposition to coercion and control.

> "There is nothing either good or bad, but thinking makes it so"

And since we presumably *think*…that we are thinking things…there is the *good*, which means there’s already its correlative *bad*. This certainly is true as it concerns the aesthetics of good taste and good sense.

The universe as a whole likely doesn’t give a shit, but the part of it we occupy seems to care. Progress depends on it. It must.

Discussion

**Empirical and Biological Constraints on Moral Norms**

1. **Premise A1 (Empirical Fact)**: Ethical norms (sets of moral values) vary widely across different societies and historical periods.

Variety(M)(“M” for moral norms)
2. **Premise A2 (Biological Fact)**: Human DNA provides universal constraints on cognitive development (including moral faculties), which allows for variation but within certain limits.

Constraints(DNA,M)(DNA imposes constraints on moral norms)
3. **Premise A3 (Social Learning Fact)**: Humans do not acquire culture (including moral norms) by instantaneous or arbitrary invention; rather, they learn from observing a limited set of behaviors and generalizing from them.

Acquire(M)↔Observation & Induction
4. **Premise A4 (Definitional/Conceptual)**: If a system S is subject to nontrivial biological constraints, then S cannot be considered purely a social or cultural construct with unbounded variation.

∀S [Constraints(DNA,S)→¬(Purely Cultural(S))]
5. **Intermediate Conclusion A (from A2, A4)**: Therefore, moral norms M are not purely cultural constructs.

Constraints(DNA,M)∧A4    ⟹    ¬(Purely Cultural(M))
6. **Premise A5 (Hypothetical Contraposition)**: If moral norms were purely cultural, then there would be no biologically imposed upper or lower bounds on their variation (i.e., they could differ indefinitely).

Purely Cultural(M)→Unbounded Variety(M)
7. **Premise A6 (Observation)**: However, moral norms exhibit not only variation (A1) but also cross-cultural commonalities and systematic limitations (from A2, A3).

¬(Unbounded Variety(M))
8. **Intermediate Conclusion B (from A5, A6)**: Hence, moral norms cannot be purely cultural in nature (reiterating A’s conclusion):

(Purely Cultural(M)→Unbounded Variety(M))∧¬(Unbounded Variety(M))    ⟹    ¬(Purely Cultural(M))
Together, A5 and A6 reinforce the conclusion that biological and social factors both determine moral norms.
