It seems that these theses do contain such general truths that all may 
agree about them. But the history of our science shows that there are many 
digressions from them. We must therefore all be prepared to give up our 
theories when these are shown to be incorrect. With regard to the newrone 
theory, I also am willing to do this as soon as it is really proved that it 
does not agree with the certified facts. But that is certainly not yet the 
case. | 
The researches of which I have had the honour to give an account to this 
illustrious audience have in view the study of the construction of the organ 
of psychic activity, the nervous system and above all the brain. The goal they 
seek to arrive at is one of the utmost difficulty, if not, indeed, in the whole 
of its compass, impossible of attainment. Science cannot stand still. 
Ultimately the object of the investigation is ourselves, the human brain, the 
organ of our own mental being. 
Here, above all, the words of the great English poet, Pope, are applicable— 
words subsequently reiterated by Gothe: 
“The proper study of mankind is man.”
