At this point in the essay, Orwell is considering whether Gandhi was a lovable man, in addition to being a good one. I have bolded a couple of fine instances of Orwell's acerbic humor.
"The autobiography leaves it uncertain whether Gandhi behaved in an inconsiderate way to his wife and children, but at any rate it makes clear that on three occasions he was willing to let his wife or a child die rather than administer the animal food prescribed by the doctor. It is true that the threatened death never actually occurred, and also that Gandhi — with, one gathers, a good deal of moral pressure in the opposite direction — always gave the patient the choice of staying alive at the price of committing a sin: still, if the decision had been solely his own, he would have forbidden the animal food, whatever the risks might be. There must, he says, be some limit to what we will do in order to remain alive, and the limit is well on this side of chicken broth. This attitude is perhaps a noble one, but, in the sense which — I think — most people would give to the word, it is inhuman. The essence of being human is that one does not seek perfection, that one is sometimes willing to commit sins for the sake of loyalty, that one does not push asceticism to the point where it makes friendly intercourse impossible, and that one is prepared in the end to be defeated and broken up by life, which is the inevitable price of fastening one's love upon other human individuals. No doubt alcohol, tobacco, and so forth, are things that a saint must avoid, but sainthood is also a thing that human beings must avoid. There is an obvious retort to this, but one should be wary about making it."
