THE HUMANIZATION OF THE TEACHING 
OF MATHEMATICS* 
WHEN the distinguished chairman of 
your mathematical conference did me the 
honor to request me to speak to you, he was 
generous enough, whether wisely or un- 
wisely, to leave the choice of a subject to 
my discretion, merely stipulating that, 
whatever. the title might be, the address 
itself should bear upon the professional 
function of those men and women who are 
engaged in teaching mathematics in second- 
ary schools. Inexpertness, it has been 
said, is the curse of the world; and one 
may, not unnaturally, feel some hesitance 
in undertaking a task that might seem to 
resemble the réle of a physician when, as 
sometimes happens, he is called upon to 
treat a patient whose health and medical 
competence surpass his own. I trust I am 
not wanting in that natural feeling. In 
the present instance two considerations 
have enabled me to overcome it. One of 
them is that, having had some experience 
in teaching mathematics in secondary 
schools, I might, it seemed to me, regard 
that experience, though it was gained more 
than a score of years ago, as giving some- 
thing like a title to be heard in your coun- 
sels. The other consideration is that, in 
regard to the teaching of mathematics, 
whether in secondary schools or in colleges, 
I have acquired a certain conviction, a 
pretty firm conviction, which, were it prop- 
erly presented, you would doubtless be gen- 
erous enough and perhaps ingenious
