BIOGRAPHICAL SKETCH. 



I, Joseph Roy Sanderson, was born in Toronto, Canada, 

 on the second of August, 1882, being the son of Joseph Sander- 

 son, manufacturer, and Caroline, his wife. 



After a training of eight years in the primary school, I took 

 a course in a Toronto business college, and then entered busi- 

 ness, to which I devoted the next four years. During the 

 latter part of this period I prepared myself, by means of private 

 instruction, for entrance into the University of Toronto, 

 where I registered as a non-matriculant in the fall of 1902. 

 After two months I was obliged to give up the year owing to 

 tailing health, and spent several months abroad. In October, 

 1903, I again registered, and in 1904 received the Senior Ma- 

 triculation standing. I then entered the course of instruction 

 in philosophy, and three years later graduated. In October, 

 1907, I enrolled as a theological student at Knox College, 

 Toronto, registering at the same time as a candidate for the 

 degree of Master of Arts at the University. My work for this 

 degree was carried on in the psychological laboratory, in con- 

 nection with the problem of 'The Relation of Accent and Pitch 

 to Musical Rhythm'. In April, 1910, I graduated from Knox 

 College, and a few months later received the degree of M.A, 

 from the University. Early in 1910 I began work, under the 

 direction of Professor A. H. Abbott, upon the present thesis, 

 for the degree of Doctor of Philosophy, my registration dating 

 from October, 1909. This work has been continued steadily 

 from that time until the present. During this time I received 

 valuable assistance in Psychology from Mr. W. G. Smith, and 

 in Ethics from Mr. G. S. Brett, while Professor J. G. Hume has, 

 during my undergraduate years, and since, supervised my 

 work in General Philosophy.
