9) All attempts to live on the land and feed oneself by one’s own labour have been unsuccessful, and could not help being unsuccessful in Russia, because it is necessary for a man of our education feeding himself by his own labour, to compete with the peasant--who fixes the prices, beating them down by his offer. But he was brought up for generations in stern life and stubborn work, while we were brought up for generations in luxurious life and idle laziness. From this it does not follow that one ought not to try to feed one’s self by one’s own labour, but only that it is impossible to expect its realisation in the first generation. 10) All calamities which are born from sex relations, from being in love, come from this, that we confuse fleshly lust with spiritual life, with--terrible to say--love; we use our reason not to condemn and limit this passion, but to adorn it with the peacock feathers of spirituality. Here is where _les extremes se touchent_. To attribute every attraction between the sexes to sex desire seems very materialistic, but, on the contrary, it is the most spiritual point of view: to distinguish from the realm of the spiritual everything which does not belong to it, in order to be able to value it highly. 11) Everything that I know is the product of my senses. My senses demonstrate to me my limits, coming in contact with the limits of other beings. This sensation, or the knowledge of limits, we recognise and cannot recognise otherwise, than as matter. And in this matter we see either only matter or beings who like us are bound by limits. The beings near to us in size, from the elephant to the insect, we know--we know their limits. The beings that are far from us in size, like atoms or like the stars, we recognise as matter only. But besides these two kinds of beings which we know by our senses, we must inevitably acknowledge still other beings (not spiritual beings like us,--that is obvious) not recognisable by our senses, but which are material, i.e., they also form limits. Such beings are atoms, ether. The presence of these beings, the admission of which is demanded by our reason, undoubtedly proves that our senses give us only a one-sided and a very limited knowledge of other beings and of the outer world. So that we can imagine for ourselves such beings endowed with such senses (_sens_) for whom ether would give the very same reality, as matter for us. (It is still unclear, but understandable.) 12) If we would always remember that our tongue was given us for the transmission of our thoughts, and the capacity of thinking for the understanding of God and His law of love, and that therefore you must talk only then when you have something good to say! But when you cannot say anything good, cannot keep back the bad--then be silent, even all your life.
