Nietzsche argued that the dogged pursuit of scientific knowledge was a form of asceticism as well, in that it caused a person to evade life — it’s hard to experience the fullness of mortality when you’re holed up in a laboratory or have your nose in a book all the time. Nietzsche also saw type-A workaholics who never have the time to enjoy the fruits of their labor as yet another category of life-denying ascetics.
