I never (take) offence at any genuine effort to wrest the truth or deduce a rational set of values from the confused phenomena of the external world. It never occurs to me to look for personal factors in the age-long battle for truth. I assume that all hands are really trying to achieve the same main object—the discovery of sound facts and the rejection of fallacies—and it strikes me as only a minor matter that different strivers may happen to see a different perspective now and then. And in matters of mere preference, as distinguished from those involving the question of truth versus fallacy, I do not see any ground whatever for acrimonious feeling. Knowing the capriciousness and complexity of the various biological and psychological factors determining likes, dislikes, interests, indifferences, and so on, one can only be astonished that any two persons have even approximately similar tastes. To resent another's different likes and interests is the summit of illogical absurdity. It is very easy to distinguish a sincere, impersonal difference of opinion and tastes from the arbitrary, ill-motivated, and irrational belittlement which springs from a hostile desire to push another down and which constitutes real offensiveness. I have no tolerance for such real offensiveness—but I greatly enjoy debating questions of truth and value with persons as sincere and devoid of malice as I am. Such debate is really a highly valuable—almost indispensable—ingredient of life; because it enables us to test our own opinions and amend them if we find them in any way erroneous or unjustified.
