82 GENERAL SCIENCE 



of one's age and bodily growth, any one who must be made to 

 do what he ought to do, and who must be compelled to refrain 

 from doing what is wrong, is not yet grown. He is yet a 

 child in the ways of right living. As persons grow older in 

 years, and come to some degree of maturity of body, it is 

 only reasonable that their conduct should give evidence of 

 growth into the better types of manhood or womanhood. 

 Knowledge gained in schools finds its chief value and most 

 fitting expression in lives that are guided more nearly aright 

 as result of such teachings. 



People who manifest no regard for the welfare and rights 

 of others may very properly be said to exhibit criminal 

 tendencies. These manifestations range all the way from 

 what is commonly called selfishness to that utter disregard 

 which does not hesitate to destroy human life for gain. 

 Not all practices included in such a sweeping classification 

 are illegal by any means, i.e., prohibited by law. The liquor 

 traffic is not only permitted in many communities but 

 legally authorized by license. It is carried on regardless of 

 an appalling list of evils that result from it both public and 

 private. The adulterations of foodstuffs, the use of harm- 

 ful preservatives, and the traffic in habit-forming drugs, 

 have been made illegal. All of them involve the robbing 

 of one person by another of health, of ability to earn a liveli- 

 hood, and of possibilities for advancement in general welfare. 

 In individual relationships in life the motto "Quid pro quo," 

 meaning to make full return in value for whatever one gets, 

 is conducive both to manhood and to good citizenship. 



Activities that largely control the development of the body 

 and mind occur during the years of childhood and youth. 

 There is lack of experience then concerning the wisdom of 

 what ought to be done. Understanding of the relationship 

 of cause and effect in matters of health, and of the conse- 

 quences of any unwise course in life, comes only through years
