The follower of a fleshless diet who throws his principles to the four winds in a trying situation lest he be thought peculiar, eccentric, different is more eager to please other men than the Overself, more interested in what their opinion is of him than in the success of his quest. How easy it is to make concessions, to give in to the herd expectations! How hard to go all the way with one's convictions, to keep one's link with integrity unbroken. Yet faithfulness is the only attitude for the man who has felt this practical pity for dumb animals.
