104 TRANSACTIONS OF THE TEXAS ACADEMY OF SCIENCE. 
If so, there is no command which may not need breaking. 
There are only two grounds, then, on which a man may be punished — 
for the good of himself or for the good of others. But science teaches 
unselfish love for others, so to harm another is to harm us all. If the 
advice in any law is good advice, the one who for any reason does not 
take that advice is to be sincerely pitied, perhaps more deeply pitied than 
the unmistakable lunatic. 
In the high-school building of a thriving Texas city the Superinten- 
dent showed me a large table and told with evident pride how he had 
forty boys leaning over that table at the same time while he hurried 
around it with his trusty rod administering to each a resounding thwack. 
The local bank-president, whose son was a pupil, extolled the perfec- 
tion of the training by saying that the instant a boy was commanded 
he obeyed, quick as flash. I answered that nothing could induce me to 
subject a boy of mine to such volitional ruin. I preferred that my boy 
should balk automatically at anything that even sounded like a com- 
mand. 
A careful and judicious expert says: Man’s temptation to lie is the 
most expensive item in all commercial transactions. 
The essence of the scientist is an ineradicable passion for verifiable 
truth. 
What example of applied science more obvious than the bicycle? The 
principle that holds it erect was familiar through the mathematics of the 
gyroscope. The ball bearings are elementary geometry, not to mention 
the tangential spokes, the pneumatic tire, the air-pump, and all the rest. 
How substitute a machine for the human type-setter? 
At the world’s fair was a machine which imitated the man by actually 
setting the type, but the solution as seen in machines in use in this city 
is vastly different. 
Instead of type, they set moulds for letters, and cast each line from 
the molten metal. 
Beautiful as a fairy tale it is to see them distribute back all these 
matrices by an application of pure geometry. 
The thousands and thousands of perceptive acts, of volitional acts in 
every small piece of type distribution are saved for higher thinking. 
And finally, all this gives but slightest hint of the many ways science 
now is storing her vast potential of physical and mental energy for ap- 
plication in service of truth and unselfishness. 
Surely her truth will make you free!
