Have you ever noticed that it is a direct result of our being temporal creatures that anything matters? The Greeks (the pre-Socratics through "Plato's cave") were seeking some unchanging atemporal permanence in being (even Heraclitus's flux was to be conceived as a permanent state of flux, with the importance on the permanence), but if you are able to meditate upon these idealized permanent forms of Being, you will quickly see that nothing can matter in such a way of being. All would simply be one unchanging unlearning undifferentiated non-something. Value happens in time, where there is a before and an after and you can either learn something, or just be a noisy spiece of shit, exchanging gases and liquids and solids and doing what stupid does and never learning a damned thing. Its up to you, here in time, where things matter because they matter to us - in time, because we are each the self-in-time. The point is that all points are points made in time, and that without time spreading out and separating the beginning from the middle from the end, the word "point" would lose all meaning. We are punctual creatures in time, inhabiting (haunting space is more accurate) only the now, punctually, as peepholes of human experience that can remember the past, or write it down for better retrieval, and we project ourselves towards the future, but we occur in the now.
