Really nothing is worse during this esoteric progress than not to try to gain an understanding of every kind of human feeling and human sensation and human life. Of course, this does not postulate the principle — this must be emphasised again and again — that we should pass over all the wrong that is done in the world without criticism, for that would be an injustice towards the world; but it postulates something else; whereas before esoteric development we may have felt a certain pleasure in finding fault with some human failing, this pleasure in finding fault with other people entirely ceases in the course of esoteric development. Who does not know in external life people who like to deliver very pertinent criticisms of other people’s faults? Not that the pertinence of judgment over human faults has to cease, not that under all circumstances, such an act as was committed, let us say, by Erasmus of Rotterdam when he wrote his book, The Praise of Folly, should be condoned; no, it may be quite justifiable to be stern against the wrongs done in the world; but in the case of one who undergoes an esoteric development every word of blame he utters or sets in motion pains him, and prepares more and more pain for him. And the sorrow at being obliged to find fault is something which can also act as a barometer of the esoteric development. The more we are still able to feel pleasure when we are obliged to find fault or when we find the world ludicrous, the less we are really ready to progress; and we must gradually gain a sort of feeling that there is, developing more and more within us, a life which makes us see these follies and errors in the world with eyes, of which one is critical, and the other filled with tears, one dry and the other wet.
