Not substantial forms which we know less.       §10. Those therefore who have been taught, that the several
Species of Substances had their distinct internal substantial Forms; and
that it was those Forms, which made the distinction of Substances
into their true Species and Genera, were led yet farther out of the way,
by having their Minds set upon fruitless Enquiries after substantial
Forms, wholly unintelligible, and whereof we have scarce so much
as any obscure, or confused Conception in general.
Locke Hum III, 6, §10, p. 445
