A. Sentience and moral status

24 arguments in Part DIR.

Underlying question: Do animals count morally?
Dominant error: Moral (arbitrary criterion)

A1

Animals aren't rational.

Rationality isn't what makes suffering matter, and the criterion would exclude humans who lack it

Full chapter
A2

Humans are superior, so we can use the inferior.

Superior abilities give no right to dominate

Full chapter
A3

Animals don't have language.

An irrelevant criterion for pain; it excludes babies and non-verbal people

Full chapter
A4

Animals don't have souls.

An unfalsifiable premise used as a public criterion

Full chapter
A5

Animals aren't conscious and don't feel pain like we do.

Contradicts the neuroscientific evidence (Cambridge Declaration, 2012; New York Declaration, 2024)

Full chapter
A6

Fish and invertebrates don't feel pain.

Growing evidence of sentience in fish, cephalopods and decapods

Full chapter
A7

No duties, no rights.

Confuses moral agents with moral patients; it would exclude children

Full chapter
A8

Animals aren't persons.

A persuasive definition: pick the concept that excludes them, then conclude they are excluded

Full chapter
A9

Rights are a human invention, only for humans.

Genetic fallacy: where a norm came from doesn't set how far it reaches

Full chapter
A10

They're just animals.

Explicit speciesism: species membership as a moral criterion, like race in racism

Full chapter
A11

It's normal for humans to be rational.

Treats individuals by what others have, not by what they have

Full chapter
A12

Human babies have the potential to be rational.

Potential doesn't confer the rights of the actual, and it doesn't cover humans without potential

Full chapter
A13

It's natural to put our own first.

Partiality lets us prefer our own; it does not let us exploit others

Full chapter
A14

Plants feel too.

No nervous system and no evidence of experience; and if they did feel, animal farming kills more plants

Full chapter
A15

Where do you draw the line? Insects? Bacteria?

Continuum fallacy: a fuzzy boundary doesn't erase clear cases

Full chapter
A16

Killing without pain isn't harm.

Death takes away good future experiences; the same holds for humans with no sense of time

Full chapter
A17

Animals are property.

Describes a legal status; doesn't justify it (as with slavery)

Full chapter
A18

What matters is the species, not the individual.

Species don't feel; individuals do

Full chapter
A19

Vegans anthropomorphize animals.

Denying similar mental states is also an error (anthropodenial), and the evidence contradicts it

Full chapter
A20

Humans have intrinsic value; animals have instrumental value.

Circular: it assumes the conclusion

Full chapter
A21

I respect animals, but humans come first

A special status no one explains and that wouldn't pass the veil of ignorance: the weight should depend on the size of the harm, not on species

Full chapter
A22

Humans suffer more than animals

Suffering more in some cases doesn't license ignoring those who suffer less; and less cognition often means more suffering and more vulnerability

Full chapter
A23

Morality exists to protect us from each other

It would also exclude babies and vulnerable people; and explaining where a practice came from does not justify it

Full chapter
A24

Species is biology, race is a social construct

A biological criterion can be as unjust as a social one: what makes discrimination unjust is giving someone's interests biased weight
