Page 142 - Or, on the other hand, we suppose the spontaneous movements to give pain, and assume that, with the pain, there will be a decrease of energy, extending to the movements that cause the evil, and thereby providing a remedy. A few repetitions of the fortuitous concurrence of pleasure and a certain movement, will lead to the forging of an acquired connection, under the law of retentiveness or contiguity, so that, at an after time, the pleasure or its idea shall evoke the proper movement at once.

Page 142 - That is to say, the lines of nervous communication through which the diffused discharge happened in this case to pass, have opened a new way to certain wide channels of escape; and, consequently, they have suddenly become lines through which a largo quantity of molecular motion is drawn, and lines which are so rendered more permeable than before.
Page 142 - Pleasure and pain can be agents of accommodation and development only if the one, pleasure, carry with it the phenomenon of "motor excess," and the other, pain, the reverse — probably some form of inhibition or of antagonistic contraction.

Page 142 - ... quantity of molecular motion is drawn, and lines which are so rendered more permeable than before. On recurrence of the circumstances, these muscular movements that were followed by success are likely to be repeated : what was at first an accidental combination of motions will now be a combination having considerable probability.
