History of Philosophy in the 17th & 18th Centuries

Locke 4: Seminar

Locke's move away from the Scholastic 'Essence'

A thing's essence for the Scholastics was its 'form', a concept absolutely central to that ('hylomorphic') framework.

Locke said if we've got to use 'essence' we Moderns can use it in two legitimate ways:

a nominal essence is a general idea (the sort a thing belongs to).

the real essence of a particular thing is its corpuscular constitution.

Any problems with this?

Primary and secondary qualities

Is there a distinction? If so, what is the criterion for telling into which category a quality falls? What is the significance of the distinction?

Might everyone be mistaken about

(a) the shape of say a bottle of Calvados standing in the middle of this table?

(b) the smell of garlic?

The tree falling unheard.

The luke-warm basin of water.
