investigation may well set itself to solve; but it 
is partly a question of what we are to 
instincts. Emotion itself is defined so 
include a cognitive and a conative attitude, as 
well as one of feeling. But the part played by 
the former aspects is not quite as clear in the 
book as it obviously is in Mr. Shand’s own mind; 
this perhaps is due to a postponement of a full 
treatment of knowledge, intelligence, and will to 
the later volume dealing with the sentiments. 
Perhaps the least convincing feature of the book 
is the source from which Mr. Shand has collected 
his facts. To observational and experimental 
data he makes scarcely any appeal. In 
support of his one hundred and forty-four pro- 
almost entirely to 
To illustrate the association of quali- 
ties in various character-types he turns to Balzac 
and La Bruyére rather than to the correlations 
of Heymans and Wiersma, or the records of the 
followers of Binet, Stern, and Freud. In the 
present stage of knowledge he is perhaps justified. 
Doubtless, field-workers will soon come forward 
to collect observations, make experiments, and 
apply statistics. And for preliminary conceptions, 
problems, and hypotheses they can go to no more 
inspiring source than Mr. Shand. 
(2) Mr. Broad’s book attempts to discover how 
much natural science can actually tell us about 
the nature of the real. But, unlike recent authors 
who have approached this question, he deals with 
physical science rather than with biological. His 
chief philosophical concerns are perception and 
causation. His problems are thus those of Mach

goes 
or Lotze rather than those of Bergson or Driesch. 
And his point of view owes much to Mr. G. E. 
Moore and Mr. Bertrand Russell. His treatment, 
however, is none the less suggestive. And his 
book provides an excellent refutation of Kant’s 
dictum that, in dealing with the traditional prob- 
lems, philosophy is concerned only with certainty 
and not with probability. 
(3) The minds of most English people (so Mr. 
H. G. Wells has declared) will only be reached, 
under present conditions, by thoughts that can 
be expressed in the meanest commonplace. In 
“Know Your Own Mind” and “Philosophy : 
What is it?’’ we have two deliberate endeavours 
to falsify this pessimistic prophecy. Mr. Glover 
and Prof. Jevons have set themselves to interest 
the average man in two of the most abstruse and 
technical branches of human knowledge—philo- 
and_ psychology. philo- 
sophers and psychologists themselves may be 
inclined to think that the point of view repre- 
sented in both is not indeed commonplace, but 
perhaps a trifle old-fashioned.

Philosophy and science, materialism and ideal- 
ism, scepticism and philosophy, personality and 
the whole—these are the time-honoured themes 
that Prof. Jevons discusses in a masterly but time- 
honoured manner. They were chosen for lectures 
delivered at the request of a branch of the 
Workers’ Educational Association. In the debates 
that followed, the burning controversies of the 
day, and the actual contributions of contemporary 
philosophers, were doubtless freely discussed; and 
so, perhaps, it was best that the main impression 
left was the enduring character of the old enduring 
questions. Often and ably as these have already 
been treated in brief, cheap, popular manuals, 
Prof. Jevons’s little book will rank among the 
best.

In his endeavour to be up-to-date, he tells us,

he has tried to catch something of the ‘cinema 
spirit.’ His metaphors, his similes, and his alle- 
gories are both vivid and picturesque. But his 
matter is not quite as up-to-date as his style. He 
gives us a revised and racy epitome of the tradi- 
tional Herbartian psychology. But the methods 
and marvels of the psychological laboratory he 
dismisses as of little practical utility and no 
popular interest. Nor does he give any reference 
which would help his reader to realise that the 
knowledge of our own minds, like most other 
knowledge, has been largely extended by careful 
observation and experiment. His main purpose, 
however—to present the subject-matter of psych- 
ology in’ a light which will be intelligible and 
interesting to the man in the street—this he has 
brilliantly fulfilled.

The Next Generation: a Study in the Physiology 
of Inheritance. By F. G. Jewett. Pp. x1+

Tue author of this skilful little book is persuaded 
that the improvement of the human breed would 
be accelerated if people knew more biology. They 
perish for lack of knowledge. “Science says 
human beings will be safer when people know the 
facts, and are influenced by them. Teachers say 
‘Give us the facts, and we will pass them on to 
the boys and girls whom we teach.’ Both man 
of science and teacher agree that the human race 
will be better able to escape certain kinds of peril 
if we let young people know what the perils are, 
and how to avoid them. Such is the purpose of 
this book.” 
The general facts of evolution, heredity, and 
development are stated with simplicity and vivid- 
ness, and on this foundation the author bases her 
instruction in regard to the culture of adolescence,
