From:
George John Romanes
To:
Charles Robert Darwin
Date:
7 Mar 1881
Source of text:
DAR 176: 216
Summary:

Responds to MS of Earthworms. An objective but arbitrary test of intelligence in animals is the ability to learn from experience. Earthworms fall on the border of intelligence. They could justly be called intelligent if they could learn by experience to manipulate some unknown, exotic leaf. CD should make clear that intelligence does not imply self-consciousness.
