said by Lola, but not known by her mistress, and
then found true....

Finally I must allude to the "discovery" made by Lola that the odours
of the human body reveal the state of the human mind--displeasure,
jealousy, lie (sic); on which the authoress observes (very justly, in a
certain sense), that these experiments make one think of the well-known
theories of the late Prof. Jaegar of Stockholm.... I am in agreement
with her on that point, because I, too, have read the "Entdeckung der
Seele" by that author; as I suppose she, too, had. I am inclined to
think that in her case (as she was experimenting with a dog) it was
only natural for her to think of these psycho-olfactory
theories--perhaps without knowing it--even before the experiments.
Therefore, the experiments themselves would always be perfectly
"genuine," but of course this genuineness is of a different sort to
what she thought it.

To conclude, the supporters of the new zoopsychology must not complain
if the views which I have set out above help in course of time to oust
their "point of view." It seems to me that even while robbing the
"thinking" animals of some of the intelligence attributed to them, and
while regarding what remains as qualitatively different from human
intelligence (e.g. through the much greater interference of
subconscious factors), we are still free to find the animals to be
perhaps even more interesting than before.

I am quite conscious of the fact that the "cases" are still few for
theories to be built upon; and some may think that I might have done
better by reporting them simply without attempting any explanation
whatever. However, I believe, that if as the result of my work the
recognition of the internal weakness of certain hypotheses--especially
in the psychological field--is generally recognized, it will not be so
harmful to have put forward some suggestions for dealing with facts
which have already been, or will be, established.

I have accordingly tried to do so, but I shall always be ready to
modify my views if new facts should persuade me that this is necessary.

many points with my own.
