My object has been to produce a work which should be as thoroughly representative of the present state of the logic of the Oxford Schools as any of the text-books of the past. The qualities which I have aimed at before all others have been clearness and consistency. For the task which I have taken upon myself I may claim one qualification—that of experience; since more than seventeen years have now elapsed since I took my first pupil in logic for the Honour School of Moderations, and during that time I have been pretty continuously engaged in studying and teaching the subject. In acknowledging my obligations to previous writers I must begin with Archbishop Whately, whose writings first gave me an interest in the subject. The works of Mill and Hamilton have of course been freely drawn upon. I have not followed either of those two great writers exclusively, but have endeavoured to assimilate what seemed best in both. To Professor Fowler I am under a special debt. I had not the privilege of personal teaching from him in logic,—as I had in some other subjects; but his book fell into my hands at an early period in my mental training, and was so thoroughly studied as to have become a permanent part of the furniture of my mind. Much the same may be said of my relation to the late Professor Jevons's Elementary Lessons in Logic.
St. George Stock was the son of St George Henry Stock senior of Castle Connell, County Sligo and Frances Wilhelmina Atkinson of Rehins Parish, Ballynahaghish, County Mayo, who were married at St Peter’s Church, Dublin on 17 December 1844. He was the fourth of six children.
In 1868 St George junior went up to the University of Oxford from Victoria College, Jersey, and was matriculated from Pembroke College on 26 October 1868.
His granddaughter Heather Grace Angel was a Hollywood actress.
The problem with Inductive logic is to determined the actual truth or falsity of propositions: The problem of the deductive logic is to determine their relative truth or falsity, given such prepositions as true, what others will follow from them. All thought involved in likeness or unlikeness, and the laws of thought are the condition of the correct thinking. "St. George Stock"
Deductive or Inductive logic upon my understanding they are not of opposite matter. There's no such thing as right or wrong in both logic its how you come to the conclusion based on reality as proof.
