The title is meant to indicate that consciousness is being examined
largely within the history of philosophy, and within the period of time
from Descartes to Ayer.
Investigators aiming to understand consciousness and minds usually try
to take account of all individual human minds, so as to have the most
data for the most encompassing induction. The problem with that approach
is that because of the vastness of the data, its results tend to be
vague, lacking the specificity of studies of individuals. On the other
hand, the problem with studies of individuals is that they cannot
guarantee generality, as the opposing method can.
This book's distinctive approach aims at a middle way, getting the best
of the two opposing methods by drawing its data from the history of
philosophy, especially the history of the great philosophers.
