p.52 Gustav Fechner... In so far as conscious impulses always relate to pleasure or unpleasure, pleasure
or unpleasure can also be conceived as psychophysically related to states of stability and instability. On this basis
is founded a hypothesis I shall develop in more detail elsewhere - the hypothesis that every psychophysical motion surmounting
the threshold of consciousness is linked with pleasure to the degree that, beyond a certain limit, it approaches total stability,
and that it is linked with unpleasure to the degree that, beyond a certain limit, it deviates from total stability; between
the two limits... there exists a certain area of perceptual indifference.
p.53 this aim we have ascribed to the mental apparatus can be classified as a special case of Fechner's
principle of the tendency toward stability, to which he relates feelings of pleasure and unpleasure.
p.53 Fechner's comment... "... that the tendency toward an aim still does not mean the aim is reached; the
aim can be reached only in approximations ..."
p.75-76 we are now on the track of a universal characteristic of drives... In this view, a drive
is an urge inherent in living organic matter for the restoration of an earlier state - one that a living being
has had to give up under the influence of external disturbing forces; it is a kind of organic elasticity, or, in a manner
of speaking, the expression of the inertia in organic life.
p.90 Given the present obscurity in the theory of drives, it would be inadvisable to reject any
idea that promises to enlighten.
p.93 [a hypothesis or theory originating from Plato which Freud is going to discuss] derives a drive from
the need to restore an earlier state.
p.98 The pleasure principle, then, is a tendency serving a function whose task is to render the mental apparatus
completely free of excitation, or to keep the amount of excitation in it constant or as low as possible.
p.99 What one cannot fly to one must limp to. ... The Scripture says that limping is no
sin.
