Sympathy

Do not attempt in the case of any man with whom you come in contact an objective valuation of him as to worth and dignity; hence do not take into consideration the badness of his will, nor the limitation of his understanding, nor the perversity of his ideas, for the first can easily   evoke hatred, the last contempt against him; but bear in mind only his sufferings, his need, his anxiety, his pains. In this way we shall continually feel ourselves related to him, sympathize with him, and instead of hatred or contempt, experience that sympathy with him which is the only precept to which the Gospel admonishes us. The standpoint of sympathy is alone suited to prevent hatred or contempt arising towards him, and not certainly the opposite one of seeking after his pretended dignity.
