Hume on the Prospects for a Scientific Psychology

Area of Science:

• Philosophy of Mind
• History of Psychology
• Epistemology

Background:

• David Hume, in "An Enquiry Concerning Human Understanding," differentiated between moralistic and scientific approaches to human nature.
• He advocated for a scientific psychology grounded in observable principles of the mind.

Purpose of the Study:

• To analyze Hume's defense of scientific psychology.
• To explore his proposed methods for psychological inquiry, including "mental geography" and a "Newtonian" approach.
• To examine his explanation of causal inference as an example of Newtonian psychology.

Main Methods:

• Hume's philosophical analysis of "An Enquiry Concerning Human Understanding."
• Examination of his distinction between descriptive psychology ("mental geography") and explanatory psychology.
• Analysis of his theory on the transfer of "vivacity" to explain causal inference.

Main Results:

• Hume defended the possibility of a scientific psychology.
• He outlined a method involving common sense, philosophical refinement, and introspection for "mental geography."
• His theory of "Newtonian psychology" aimed to identify underlying mental laws and forces, exemplified by his account of causal inference.

Conclusions:

• Hume's work provides a foundational argument for scientific psychology.
• His proposed methods and theories represent an early, speculative attempt at a systematic, law-based understanding of the mind.
• The explanation of causal inference through the transfer of vivacity serves as a key example of his envisioned psychological science.
