No Compromise – No Political Trading (1899)
                                    
“Hence the one-sided errors—ces erreurs d'idée fixe—which we cannot escape when we stand too near to one or the other party; either deceives, yet does it unaware, and we confide most willingly in those who think as we do. But if we are by chance of such indifferent nature that we, without special predilection, keep in continual intercourse with all, then we are bewildered by the perfect self-confidence of either party, and our judgement is neutralised in the most depressing manner.”
