Philosophers, as things now stand, are all too fond of offering criticism from on high instead of studying and understanding things from within. They often behave toward phenomenology as Berkeley – otherwise a brilliant philosopher and psychologist – behaved two centuries ago toward the then newly established infinitesimal calculus. He thought he could prove, by his logically sharp but superficial criticism, this sort of mathematical analysis to be completely groundless extravagance, a vacuous game played with empty abstractions. It is utterly beyond doubt that phenomenology, new and most fertile, will overcome all resistance and stupidity and will enjoy enormous development, just as the infinitesimal mathematics that was so alien to its contemporaries did, and just as exact physics, in opposition to the brilliantly obscure nature philosophy of the Renaissance, has done since the time of Galileo.
