Every animal, including also la bete philosophe instinctively strives for the optimal beneficial conditions in which it can let out all its power and attain the strongest feeling of its strength. Every animal in the same instinctual way and with a refined sense of smell that "is loftier than all reason" dislikes any kind of trouble maker or barrier which lies or which could lie in his way to these optimal conditions (I'm not speaking about his path to "happiness" but about his way to power, to action, to his most powerful deeds, and, in most cases, really about his way to unhappiness). Thus, the philosopher dislikes marriage as well as what might persuade him into it; marriage is a barrier and a disaster along his route to the optimal. What great philosopher up to now has been married? Heraclitus, Plato, Descartes, Spinoza, Leitniz, Kant, Schopenhauer; none of these got married. What's more, we cannot even imagine them married. A married philosopher belongs in a comedy, that's my principle. And Socrates, the exception, the malicious Socrates, it appears, got married ironically to demonstrate this very principle.
