What is involved in the existence of general propositions
The two factors of reasoning
Sagacity
The part played by association by similarity
The intellectual contrast between brute and man: association by similarity the fundamental human distinction
Different orders of human genius
CHAPTER XXIII. THE PRODUCTION OF MOVEMENT
The diffusive wave
Every sensation produces reflex effects on the whole organism
CHAPTER XXIV. INSTINCT
Its definition
Instincts not always blind or invariable
Two principles of non-uniformity in instincts:
1) Their inhibition by habits
2) Their transitoriness
Man has more instincts than any other mammal
Reflex impulses
Imitation
Emulation
Pugnacity
Sympathy
The hunting instinct
Fear
Acquisitiveness
Constructiveness
Play
Curiosity
Sociability and shyness
Secretiveness
Cleanliness
Love
Maternal love
CHAPTER XXV. THE EMOTIONS
Instinctive reaction and emotional expression shade imperceptibly into each other
The expression of grief; of fear; of hatred
"Emotion is a consequence, not the cause, of the bodily expression"
Difficulty of testing this view
Objections to it discussed
The subtler emotions
No special brain-centres for emotion
Emotional differences between individuals
The genesis of the various emotions
CHAPTER XXVI. WILL
Voluntary movements: they presuppose a memory of involuntary movements
Kinæsthetic impressions
No need to assume feelings of innervation
The ´mental cue´ for a movement may be an image of its visual or auditory effects as well as an image of the way it feels
Ideo motor action
Action after deliberation
Five types of decision
The feeling of effort
Unhealthiness of will:
1) The explosive type
2) The obstructed type
Pleasure and pain are not othe only springs of action
All consciousness is impulsive
What we will depends on what idea dominates in our mind
The idea´s outward effects follow from the cerebral machinery
Effort of attention to a naturally repugnant idea is the essential feature of willing
The free-will controversy
"Psychology, as a science, can safely postulate determinism, even if free-will be true"
The education of the Will
Hypothetical brain-schemes
CHAPTER XXVII. HYPNOTISM

CHAPTER XXVIII. NECESSARY TRUTHS AND THE EFFECTS OF EXPERIENCE
Programme of the chapter
Elementary feelings are innate
The question refers to their combinations
What is meant by ´experience´
Spencer on ancestral experience
Two ways in which new cerebral structure arises: the ´back-door´ and the ´front-door´ way
The genesis of the natural sci
Scientific conceptions arise as accidental variations
The genesis of the pure sciences
Series of evenly increasing terms
The principle of mediate comparison
That of skipped intermediaries
Classification
Predication
Formal logic
Mathematical propositions
Arithmetic
Geometry
Our doctrine is the same as Locke´s
Relations of ideas v. couplings of things
The natural sciences are inward ideal schemes with which the order of nature proves congruent
Metaphysical principles are properly only postulates
Æsthetic and moral principles are quite incongruent with the order of nature
Summary of what precedes
The origin of instincts
Insufficiency of proof for the transmission to the next generation of acquired habits
Weismann´s views
