“We race toward the future at the velocity of the present.”

“Real generosity towards the future lies in giving all to the present.”

“True generosity toward the future consists in giving everything to the present.”

“...when our minds are unconsciously in the future, the present disappears; it is simply not available to us. We substitute heading toward our lives for actually living.”

“Man can only be certain about the present moment. But is that quite true either? Can he really know the present? Is he in a position to make any judgment about it? Certainly not. For how can a person with no knowledge of the future understand the meaning of the present? If we do not know what future the present is leading us toward, how can we say whether this present is good or bad, whether it deserves our concurrence, or our suspicion, or our hatred?”

“Give me the positions and velocities of all the particles in the universe, and I will predict the future.”
