Mind begins with clear state
We use our senses to find out about the world
Sense data or qualities
World existing outside of us
Primary qualities: Scientific characteristics of an object
Substrata – what truly exists / reality
a. HINDU MYSTIC – praying and sitting on a bed of nails
What supports the Earth? A white elephant
What supports the white elephant? A giant tortoise
What supports the giant tortoise? “I KNOW NOT WHAT”
Empiricists admit limitation of knowledge LOCKE – Our knowledge is only as far as our senses can take us Does not know what quality proves substratum FOR EMPIRICISTS HUMAN KNOWLEDGE IS “LIMITED”
Book
a. SUBSTRATUM
– metaphysical idea
Where primary and secondary qualities adhere
Exists in all things
Secondary qualities: Do not make object what it is, attach themselves to object. Qualities are merely accidental to the object.
(Color of marker: A blue marker if changed to color red is still a marker)
Primary Qualities: Makes object what it is. If quality is missing, the object will not be what it is. 2. GEORGE BERKELEY – ESSE EST PERCIPI = TO BE IS TO BE PERCEIVED
