a personal search for the meaning of life
The purchase of the book can be recommended to anyone who
  • wants to get an idea of how strongly the spirit of materialism can be rooted in the mental structure of scientists

The following quotations reflect the mental atmosphere of the book quite well.

 

A bleak philosophy of life follows such views...
Humans as Machines?

Some fears and hopes about future hybrid beings (German)The future of humans as hybrid beings: fears and expectations (German)

On the title of the book, page 7:
The Title of this book has been chosen to make plain to my readers and also to keep before myself the fact that it is an attempt at an objective description of human behaviour. A purely objective description is not yet possible; the showman cannot help being part of the show...

On the practical value for doctors, page 7:
It is a plea for many different things, but especially for the physiological, material attitude of patients and doctors towards life and its discomforts and for the exclusion of magic and the supernatural from the treatment of the human machine.

On making people sick, page 9:
It is fatally easy to turn a sick person into a very sick person by increasing his anxiety...

On the volatility of gods, page 12:
Only as the gods become less and less personal, and finally evaporate, does the objective viewpoint become possible.

On the scientific creed of causality, page 12:
The logical system based on this objective approach is science. It is not teleological like religion. It is not an enquirey into purposes, but into causes.

On causality, page 13:
...effects follow causes and depend entirely upon them...

On the literary style fit for science, page 14:
Science must be written in prose, in objective language, and its literature will ultimately be a collection of formulae and statistics.

On psychology not being measurable, page 15:
...so the egocentric, subjective physiology and psychology are still taught, and their concepts still accepted, being more easily understood, though it is now realised that the subjective attitude cannot be scientific; the results of its experiments cannot be measured.

On the need and inability to be objective always, page 17:
But I will try whenever possible to be objective, and I ask my readers to be objective too, and to feel that they are on firmer ground when they are standing outside the subject, viewing it as dispassionately as possible.
The only thing which our brains cannot view objectively or experiment with, therefore possibly the only absolutely unknowable thing, is the working of our own brains
.

On the classical of motion as the only cause, page 17:
...as we cannot conceive any movements except as the product and resultant of other movements...

On the soul being a semi-scientific concept, page 17:
Lately, with the growth of a semi-educated public, with but lightly disciplined modes of thought and brought up with a reverence for the word-made-flesh, there have developed many animistic philosophies, expressed and propagated by an enormous semi-scientific literature, into which the concept "soul" has crept back.

A bold assumption not yet proven, page 18:
Psychoanalysts "explain" behaviour by saying that it is motivated and controlled by various urges and repressions which they have exalted into spiritual entities - the Libido, the Censor. They are apparently content with having done this. They do not enquire further. If they did, they would find nothing but the structure of the organism and its responses to its environment.

On the volatility of free will, page 19:
The more is learnt about the physiology of any action, the less it is seen to depend upon "Will".

The soul is being driven out of reality, page 19:
The search for the possible seat of the soul is drawing to an end in the same way as did the search for the earthly paradise. With every new discovery we find places where it is not.

On duality being unacceptable, page 20:
Except for the pure idealist, belief in Free Will necessitates a belief in a duality, a belief in what can be called material and what can be called immaterial. It also involves the belief that these can affect each other. Whatever his conception of matter, whether in terms of wave or particle, a scientist cannot conceive it as being affected - that is, its motion as being initiated, stopped or deflected - by something other than matter. Such an occurrence would be in the class of miracles, and on a level with that which Joshua performed in causing the sun to stand still; in fact it would be even more miraculous, because Joshua was not immaterial and he did exert some material force; he spoke to the sun.

On the pillars of science, page 21:
...though science has been built upon determinismis, religion, politics and law are based on Free Will.

After the introduction to the book, there follow a number of chapters where physiological and psychological phenomena are described in terms of a purely materialist-behaviouristic language.

  In general, the assertions made in the introduction of this book have almost all been challenged by the findings of quantum physics. Quantum physics was established during the 1920ies and 1930ies.

Quotations from modern scientists seriously questioning the ubiquious validity of causality are given by the following links:

The User Illusion: The mystery of consciousnessTor Norretranders
Mind, Matter, and Quantum MechanicsHenry Stapp
A jesuit in evolutionTeilhard de Chardin
A neurologist interprets quantum physics in relation to human consciousnessJohn Eccles
A philosopher on determinism and free willKarl Popper

A deterministic view of the world, some ideas in GermanKepler`s laws of planetary motion: a seemingly perfect example of the validity of mechanistic determinism

A deterministic view of the world, some ideas in German

Another example of a deterministic view of the world: ballistics

Where are spirit and soul in such a "Weltanschauung"?
Do humans function like other pieces of machinery?

Aldous Huxley, 1894-1963, about drug-induced experiences of the selfAldous Huxlex, a contemporary of Yerbury Dent, thought quite differently. Huxley attaches great importances the mystic strangeness of the inner world of fancy and imagination.
