The Moral Instinct
Definition
Morality is a system of
complex behaviors
which evolved to
promote social cohesion
and hence contribute to
individual survival.
The Moral Instinct
• Universal innate tool-kit created thru Darwinian
selection and modified by cultural and religious
influence.
• Modeled on Chomsky’s universal language.
• Largely unconscious without conscious reasoning.
• Emotion first. Reason follows post-hoc.
• Generally involves issues of harm, fairness and
disgust.
• Damage causes deficit in moral judgment.
Morality
The Moral System
• Complex interrelationship of somatic sensations,
limbic input, and frontal lobe restraint and
modification.
• Unconscious- fast, automatic, limited and
involuntary.
• Conscious: slow, deliberate, wide-ranging and
thoughtful.
The Social Imperative
• Groups survive better than individuals in
securing food and in protection from
predators.
• Animals demonstrate mutualism, empathy and
cooperative territorialism.
• A system of complex behaviors evolved to
promote social cohesion and hence contribute
to individual survival.
• Cooperation and reciprocity.
Moral v. Social Rules
• Moral Rules are universal principles with
early childhood acquisition that govern
welfare and fairness and usually expressed
unconsciously.
• Social Rules govern group coordination
which are acquired thru learning and tend to
be more relative and less imperative.

inaccessible systems.

behaviors are not limited.
• Religions and laws do not create moral judgments.
They have adopted them.
• Rationality and utilitarianism do not always
prevail.
