“We appear to have a tendency to consider smaller beings “less sentient” and less morally important than bigger ones. It somehow feels like a lobster is much more likely to be sentient than, say, an ant. However, this intuition is far from justified, since an ant brain actually has more than twice as many neurons than the brain of a lobster, while bees and cockroaches both have about ten times as many neurons as a lobster. So, when we think about insects and small beings in general, it is worth planting this flag in the front of our minds: we should not be swayed to believe that these beings matter less simply because they are small.”
