Only the fundamentals of deductive and inductive logic have received attention. Moreover emphasis has been given to those phases which appear to commend themselves because of their practical value.
Further than this we trust that the book may fulfill in some small way the larger mission of inspiring better thinking and, in consequence, of leading to a more serviceable citizenship.
Surely as civilization advances it is with the expectation of giving greater significance to the assumption “that man is a _rational_ animal.”
I am indebted to a number of writers on logic, notably to Mill, Lotze, Keynes, Hibben, Fowler, Aikins, Hyslop, Creighton and Jevons. I am likewise under obligation to that large body of students who, by frankly revealing their difficulties, have given me a different point of view.
For constructive criticism and definite encouragement I owe a personal debt of gratitude to Prof. Charles Gray Shaw of New York University, to Prof. Frank D. Blodgett of the Oneonta Normal School and to Prin. A. C. MacLachlan of the Jamaica Training School for Teachers.
