So this is why we philosophize: because there is desire, because there is absence in presence, deadness in life; and also because there is our power that is not yet power; and also because there is alienation, the loss of what we thought we had acquired and the gap between the deed and doing, between the said and the saying; and finally because we cannot evade this: testifying to the presence of the lack with our speech. In truth, how can we not philosophize?
