Gottfried Wilhelm Leibniz (1646-1716)
{One of the inventors of calculus}
Background
Locke's view that
"There is nothing in the intellect
which was not first in the senses."
Leibniz's response:
"Nothing, except the intellect itself."
i.e., to have experience, there must
first be a mind that is attentive and
prepared
Note implication:
Perceiving/knowing is not mechanical;
mind is not a passive mirror, but an
active and selective meaning-maker
Leibniz's View of Consciousness
- Denied Descartes' sharp division
between conscious minds &
non-conscious matter
- Asserted that consciousness is a
matter of degree:
-- World is made of monads: an
infinite number of particles
which are conscious
-- Monads combine to give:
- extension to physical bodies
- & also consciousness to a degree
{just as in integral calculus tiny bits add
up to explain a function within limits}
-- Monads have no "windows,"
nor do they change due to
outside influence; monads
change from within, by "unfolding"
- Why do different things change in
a coordinated fashion
(e.g., mental/physical events)?
Due to a Harmony, pre-established
by God.
{psycho-physical parallelism}
Implications for psychology:
- Continuum of degrees of consciousness
in plants, animals & humans
{anticipates Fechner's mind-matter
continuum, and Freudian
subconscious}
- Rejection of the idea that mind is empty
implies "nativism," a view that any
inquiry needs at least some
background.
Compare the expression used in
hermeneutics:
"no understanding without
pre-understanding"
- Emphasises "unfolding" in human
development;
anticipates Piaget-type views of
development
Giovanni Battista Vico (1668-1704):
Four Types of Knowledge:
- Scienza -> verum
"universal a priori truths"
as in mathematics
- Coscienza -> certum
"external knowledge",
acquaintance with fact
- Storia ideale eterna -> forms
"eternal truths" (Plato)
- Per Causus -> creations
"intentional 'inner' knowledge"
Anticipates Herder's notion of Volkseele or "common sense"
of a language community of peoples
Predecessor of Volkerpsychologie
- Hermeneutics of life history
- Many perspectives and
interpretations of life through
language, art, myth, religion ...
Social Evolution - stages of
psychological development
through symbolic life.
- Understand thoughts and feelings
through language, art, custom,...
