(Because) the notion of absolute truth is difficult to sustain outside the context of religion, ethical conduct is not something we engage in because it is somehow right in itself but because, like ourselves, all others desire to be happy and to avoid suffering. Given that this is a natural disposition, shared by all, it follows that each individual has a right to pursue this goal. Accordingly, I suggest that one of the things which determines whether an act is ethical or not is its effect on others' experience or expectation of happiness.
Paradoxical as it may seem, the purposeful life has no content, no point. It hurries on and on, and misses everything. Not hurrying, the purposeless life misses nothing, for it is only when there is no goal and no rush that the human senses are fully open to receive the world.
Universal peace as a result of cumulative effort through centuries past might come into existence quickly - not unlike a crystal that suddenly forms in a solution which has been slowly prepared. Science is but a perversion of itself unless it has as its ultimate goal the betterment of humanity.
The goal lies away from the sensual world. It is not a rejection of the sensual world, but understanding it so well that we no longer seek it as an end in itself. We no longer expect the sensory world to satisfy us. We no longer demand that sensory consciousness be anything other than an existing condition that we can use skillfully according to time and place.
Each man lives for himself, uses his freedom to achieve his personal goals, and feels with his whole being that right now he can or cannot do such-and-such an action; but as soon as he does it, this action, committed at a certain moment in time, becomes irreversible, and makes itself the property of history, in which is has not a free but a predestined significance.
If you are pleased with what you are, you have stopped already. If you say, "It is enough," you are lost. Keep on walking, moving forward, trying for the goal.
