Chomsky would also argue that both baby Humans and baby
Hedgehogs are capable of what the logical call 'inductive reasoning,'
which is the ability to produce, "the odds are that if I do X then Y is
likely to happen." Inductive reasoning enjoys the possibilities and is
sometimes nervous around them. But it's cousin, referred to as 'deductive
reasoning,' is a capacity of people, not Hedgehogs. Deductive reasoning,
