Moral Dilemmas

Recall the divide on abortion. We often disagree on what is morally right or wrong.

Here is The 10 biggest moral dilemmas in science.

Should we … Give other animals rights?

For centuries, ethical debates have foused on certain fundamental, inalienable rights (regardless of what you do or how evil you are). But should animals be granted similar protections?

Should we … Give other animals rights?

Should we … Genetically engineer our children?

Should we … Make everyone ‘normal’?

“Imagine a pill or therapy capable of rewiring your neural circuitry so as to make you more empathetic: one that decreases aggression, and causes your capacity for moral reasoning and tendency to forgive to go through the roof. Wouldn’t the world be a better place if we were all encouraged to have it? In fact, if human happiness lay on the other side of a tablet, why not embrace utopia and prescribe it by force?”

Moral philosophy

We will focus on utilitarianism and categorical imperative. Check here for more theories of moral philosophy.

Utilitarianism

The greatest happiness of the greatest number is the foundation of morals and legislation.

— Jeremy Bentham, COLLECTED WORKS (1843)

- Are Consequences All That Matter?
- Should We Be Equally Concerned for Everyone?

Categorical Imperative (or Deontology)

Kant’s argument

More on Kant’s argument

The Case of the Inquiring Murderer.

-Here is an intro by crash course on Kant and Categorical Imperative.

What do you think of Kant’s argument?

White lies? When saving lives? This points to the main difficulty for the belief in absolute rules: Shouldn’t a rule be broken when following it would be disastrous?

Should that principle be dismissed?

Other lingering points

Retributivism
