There is the alternative possibility that Mr. Wilson was convinced that, after he had given a subject mature consideration and reached a decision, his judgment was right or at least better than that of any adviser. A conviction of this nature, if it existed, would naturally have caused him to feel impatient with any one who attempted to controvert his decisions and would tend to make him believe that improper motives induced the opposition or criticism. This alternative, which is based of necessity on a presumption as to the temperament of Mr. Wilson that an unprejudiced and cautious student of personality would hesitate to adopt, I mention only because there were many who believed it to be the correct explanation of his attitude. In view of my intimate relations with the President prior to the Paris Conference I feel that in justice to him I should say that he did not, except on rare occasions, resent criticism of a proposed course of action, and, while he seemed in a measure changed after departing from the United States in December, 1918, I do not think that the change was sufficient to justify the presumption of self-assurance which it would be necessary to adopt if the alternative possibility is considered to furnish the better explanation. It is, however, natural, considering what occurred at Paris, to search out the reason or reasons for the President's evident unwillingness to listen to advice when he did not solicit it, and for his failure to take all the American Commissioners into his confidence. But to attempt to dissect the mentality and to analyze the intellectual processes of Woodrow Wilson is not my purpose. It would only invite discussion and controversy as to the truth of the premises and the accuracy of the deductions reached. The facts will be presented and to an extent the impressions made upon me at the time will be reviewed, but impressions of that character which are not the result of comparison with subsequent events and of mature deliberation are not always justified. They may later prove to be partially or wholly wrong. They have the value, nevertheless, of explaining in many cases why I did or did not do certain things, and of disclosing the state of mind that in a measure determined my conduct which without this recital of contemporaneous impressions might mystify one familiar with what afterwards took place. The notes, letters, and memoranda which are quoted in the succeeding pages, as well as the opinions and beliefs held at the time (of which, in accordance with a practice of years, I kept a record supplementing my daily journal of events), should be weighed and measured by the situation which existed when they were written and not alone in the light of the complete review of the proceedings. In forming an opinion as to my differences with the President it should be the reader's endeavor to place himself in my position at the time and not judge them solely by the results of the negotiations at Paris.
