Every other activity of man is only lawful when these have first been satisfied. In whatever department a man thinks his calling lies, whether in governing the people, in protecting his countrymen, in officiating at divine services, in teaching, in inventing the means of increasing the delights of life, in discovering the laws of the universe, in incorporating eternal truths in artistic images, the first and most unquestionable duty of a reasonable man will always consist in taking part in the struggle with nature for preserving his own life and the lives of other men. This duty must always rank first, because the most necessary thing for men is life: and therefore, in order to protect and to teach men, and to make their lives more agreeable, it is necessary to keep this very life; while by not taking part in the struggle, and by swallowing up the labour of others, other lives are destroyed. And it is folly and impossible to endeavour to serve men while destroying their lives. Man's duty to acquire the means of living through the struggle with nature will always be unquestionably the very first of all duties, because it is the law of life, the violation of which unavoidably brings with it a punishment by destroying the bodily or mental life of man. If a man, living alone, free himself from the duty of struggling with nature, he will be at once punished by the perishing of his body. But if a man free himself from this duty by compelling other men to fulfil it for him, in ruining their lives, he will be at once punished by the destruction of his reasonable life; that is, of the life which has a reasonable sense in it. I had been so perverted by my antecedents, and this first and unquestionable law of God or nature is so hidden in our present world, that the fulfilling of it had seemed to me strange, and I was afraid and ashamed of it, as if the fulfilment, and not the violation, of this eternal and unquestionable law were strange, unnatural, and shameful. At first it seemed to me, that, in order to fulfil this law, some sort of accommodation was necessary, some established association of fellow-thinkers, the consent of the family, and life in the country (not in town): then I felt ashamed, as if I were putting myself forward in performing things so unusual to our life as bodily labour, and I did not know how to begin. But I needed only to understand that this was not some exclusive activity, which I have to invent and arrange, but that it was merely returning from the false condition in which I had lived to a natural one, merely rectifying that lie in which I had been living,--I had only to acknowledge all this, and all the difficulties vanished.
