# Debate 1
|
||
|
|
|
||
|
|
## Proposition
|
||
|
|
> "bivalves are sentient because they have a brain."
|
||
|
|
|
||
|
|
## Argument
|
||
|
|
|
||
|
|
1. "The definition of brain needs to apply to all species... Not being such, it is speciesist intentionally.
|
||
|
|
2. If the definition of a brain doesn't apply to sponges, then your definition of brain is speciesist on your own lights.

## Analysis
|
||
|
|
|
||
|
|
1. If your definition of a brain is so broad that it captures structures like cerebral ganglia, I don't see how you're not committed to the proposition that my body contains multiple brains. Do you sign off on that?
