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,...
