I Do Not Believe That

Ethics Is Inescapable.

If We Compare A Severely Defective Human Infant With A Nonhuman Animal, A Dog Or A Pig, For Example, We Will Often Find The Nonhuman To Have Superior Capacities, Both Actual And Potential, For Rationality, Self-consciousness, Communication And Anything Else That Can Plausibly Be Considered Morally Significant.

Pain And Suffering Are In Themselves Bad And Should Be Prevented Or Minimized, Irrespective Of The Race, Sex, Or Species Of The Being That Suffers. How Bad A Pain Is Depends On How Intense It Is And How Long It Lasts, But Pain Of The Same Intensity And Duration Are Equally Bad, Whether Felt By Humans Or Animals.

We Don't Usually Think Of What We Eat As A Matter Of Ethics. Stealing, Lying, Hurting People - These Acts Are Obviously Relevant To Our Moral Character. In Ancient Greece And Rome, Ethical Choices About Food Were Considered At Least As Significant As Ethical Choices About Sex.

Sci-fi Is Often A Metaphor. I Think It's More The Themes And Questions That Science Fiction Raises Rather Than The Exact Predictions That Should Guide Us.
