Good meeting we watched a video on what is wrong with the world then a positive viewpoint from Sian Stephenson. After tea we read the following. Interesting two people could only see one image of the young woman or the old woman. I could see both and they changed on their own.
It looks like there is a white square in the
center of this figure, but when we study the image, it becomes clear
that there are only four partial circles. The square has been imposed
by our visual system, whose edge detectors have been fooled. Can we
know that the black shapes are more real than the white one? Yes,
because the square doesn’t survive our efforts to locate it — its
edges literally disappear. A little investigation and we see that its
form has been merely implied.
What could we say to a skeptic who insisted that the
white square is just as real as the three-quarter circles and that
its disappearance is nothing more than, as you say, “a relatively
rare — and deliberately cultivated — experience”? All we could
do is urge him to look more closely. The same is true about the
conventional sense of self — the feeling of being a subject inside
your head, a locus of consciousness behind your eyes, a thinker in
addition to the flow of thoughts. This form of subjectivity does not
survive scrutiny. If you really look for what you are calling “I,”
this feeling will disappear. In fact, it is easier to experience
consciousness without the feeling of self than it is to banish the
white square in the above image.

The
personal development quest probably involves the questions:
Any
answer or answers to these and other important questions in turn
raise the question, 'How do you know that?'
This
means that we need to know how we know things and to what degree
we can trust the answers and the questions.
It
becomes more important when people have turned to powerful people,
organisations, or cultures which claim to ask the right questions
and give the right answers. We need to be able to ask, 'How do
they know this?' and know what sort of answers are going to be
satisfactory.
In
the well known illusion, the two horizontal lines are equal in
length, but one looks longer than the other.
Now
the top line looks longer to me than the bottom one. However, both
are really the same length. So what am I seeing? Am I seeing the
real lines? Presumably not, because the real lines are the same
length and these look different.
|
So
where are the illusory lines? Clearly not where I am looking
because the real lines are there. And they are the same length. So
I am not looking where the real lines are, but somewhere else.
Also I am not looking at the real lines, but at something else.
Something has got to be wrong with my perception or my thinking
here. Something is deceiving me.

Consider
this classic illusion below:
|
Some
people quite clearly see a picture of a young woman. Others see a
picture of an old woman. Sometimes people quarrel quite vigorously
and maintain that their impression is correct. When we get used to
the picture we see the two pictures of the old woman and the young
one. But others see other things in the picture! Can you see the
rat?
|
Once
again, we have the question where is the picture of the young
woman, when the picture appears to be that of an old woman? Where
is the picture of the old woman when the picture appears to be
that of the young woman? What am I looking at, in either case?
Clearly not a picture of an old womanor a young woman,
and clearly not both! Nor is it a changing picture, because by all
other tests, the ink on the drawing does not change. The change
occurs in our own minds. And what we see is clearly in our own
minds. Now what does this tell us when we perceive 'normally?'
Yet
even when we observe common objects, such as bent sticks in the
water, and train lines that appear to converge at a distance, we
are clearly being deceived. We are even more likely to be deceived
when we consider ideas.
Can we therefore ever be arrogantly sure of being right about
ideas again?
We
could claim that we know that the illusions are false because
under some conditions we can 'see' accurately. Scientists usually
specify very accurately the conditions under which they carried
out their experiments. Yet, if the conditions are not the same on
further occasions, how can we believe that the results are true.
(Does what works in the lab work in the field?) In the same way,
are we seeing a straight stick in the water which looks bent. Or
are we seeing, outside the water, a bent stick which looks
straight? Which is true?
Further,
what can we as humans actually know? Can we know about life after
death? About reincarnation? Can we know about our real nature?
What is knowledge
