We become more and more aware that what we think about the world is not what the world is but what the human animal sees of the world.

We only see what we want to see, and hear what we want to hear. We don’t perceive things the way they are. We have the habit of dreaming with no basis in reality. We literally dream things up in our imaginations. Because we don’t understand something, we make an assumption about the meaning, and when the truth comes out, the bubble of our dream pops and we find out it was not what we thought it was at all.

Why does the eye see more clearly when asleep than the imagination when awake?

When we're awake, we see what we need to see. When we're asleep, we see what is really there.

Animals do not possess this ability. We call it “self-awareness” or the ability to think about your very thought process.

How can you prove whether at this moment we are sleeping, and all our thoughts are a dream; or whether we are awake, and talking to one another in the waking state?

Supposing there was no intelligence behind the universe, no creative mind. In that case, nobody designed my brain for the purpose of thinking. It is merely that when the atoms inside my skull happen, for physical or chemical reasons, to arrange themselves in a certain way, this gives me, as a by-product, the sensation I call thought. But, if so, how can I trust my own thinking to be true? It's like upsetting a milk jug and hoping that the way it splashes itself will give you a map of London. But if I can't trust my own thinking, of course I can't trust the arguments leading to Atheism, and therefore have no reason to be an Atheist, or anything else. Unless I believe in God, I cannot believe in thought: so I can never use thought to disbelieve in God.

We don’t see the truth because we are blind. What blinds us are all those false beliefs we have in our mind. We have the need to be right and to make others wrong. We trust what we believe, and our beliefs set us up for suffering.

The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.

Clarity of perception and thought evidently requires that we be generally aware of how our experience is shaped by the insight (clear or confused) provided by the theories that are implicit or explicit in our general ways of thinking.

Our eyes are holden that we cannot see things that stare us in the face, until the hour arrives when the mind is ripened; then we behold them, and the time when we saw them not is like a dream.

Seeing clearly means that you’re smart enough to know when a project is doomed, or brave enough to persevere when your colleagues are fleeing for the hills. Abandoning your worldview in order to try on someone else’s is the first step in being able to see things as they are.

The human mind may perceive truth only through thinking, as is clear from Augustine.

You see, all our ordinary views of things are no good, they do not lead anywhere. It is necessary to think differently, and this means to see things we do not see now, and not to see things we see now. And this last is perhaps the most difficult, because we are accustomed to see certain things: it is a great sacrifice not to see the things we are accustomed to see. We are accustomed to think that we live in a more or less comfortable world. Certainly there are unpleasant things, such as wars and revolutions, but on the whole it is a comfortable and well-meaning world. It is most difficult to get rid of this idea of a well-meaning world. And then we must understand that we do not see things themselves at all. We see like in Plato’s allegory of the cave only the reflections of things, so that what we see has lost all reality. We must realize how often we are governed and controlled not by the things themselves but by our ideas of things, our views of things, our picture of things. This is the most interesting thing. Try to think about it.
