Understanding human perception by human-made illusions

yogachara theory and i'm thinking here about three nature theory and three naturelessness theory suggests to us that we are simply wired for certain illusions and among them is 00:29:19 the illusion of immediacy um and we're wired to thematize our experience through the framework of subject object duality i often compare this to the way that we're wired for certain 00:29:31 optical illusions for instance you don't have to learn to see the mueller liar illusion as an illusion we all see it as an illusion and it's because of the way our visual system has evolved and there are lots of other optical illusions like 00:29:44 that the color five phenomenon for instance and so forth yogachara really takes very seriously the idea that from beginning with time we've evolved karmic predispositions to certain kinds of 00:29:55 illusions and these are some of them and of course a little bit of reflection shows that that duality has to be illusory um after all um we are 00:30:09 not subject pure subjects standing outside of the world of our experience confronting a world of objects some of them outer and some of them inner that's the vedanta position that ain't the buddhist position instead what we are is 00:30:24 organisms and again i will set aside all of the debates we might have about how those organisms are constituted but we are organisms embedded in an environment and our bodies our sense faculties are 00:30:37 part of the world in which we find ourselves as a consequence our subjectivity our own engagement with the world is constituted not by standing outside and detecting things but rather by being 00:30:51 embedded in the world and the only way that we could possibly become aware of any object whether it's a tree or an apple or a thought or a feeling is to construct that as an object in our field 00:31:04 of consciousness even if in doing so we manage to hide from ourselves the fact that we are constructing it

another aspect to cognitive illusion here is the illusion um that our sense perception is something that 00:22:02 is transparent and simply delivering us a world as a telescope does and not as a cognitive not as a kaleidoscope does as a consequence then the sense that we 00:22:15 know our own cognitive states directly and accurately through inner sense as well of outer sense has got to be a cognitive illusion as well are of the the sortals or the concepts that we use 00:22:28 in order to introspect are just as opaque to us as our senses are and give us just as a non-transparent access to our inner world as our senses give to the outer 00:22:42 world

the illusion that pervades our sense perception is that what we experience is something external to us that somehow 00:20:10 we've got a world that exists as it is independent of us and that we simply happen to be perfect world detectors and we wander through it detecting things just as they are

our mind functions as dharma yearly 00:19:43 emphasized as an instrument through which we have access to the world

cognitive illusion and immediate experience perspectives 00:01:44 from buddhist philosophy

so here's a straightforward question what color are the strawberries in this photograph the red right wrong those strawberries are gray if you don't 00:00:12 believe me we look for one of the reddest looking patches on this image cut it out now what color is that it's great right but when you put it back on 00:00:25 the image it's red again it's weird right this illusion was created by a Japanese researcher named Akiyoshi Kitaoka and it hinges on something called color constancy it's an incredible visual 00:00:39 phenomenon by which the color of an object appears to stay more or less the same regardless of the lighting conditions under which you see it or the lighting conditions under which your brain thinks you're seeing it

Why is it nearly invisible?

Truths are illusions which we have forgotten are illusions- they are metaphors that have become worn out and have been drained of sensuous force, coins which have lost their embossing and are now considered as metal and no longer as coins.

It is only by means of forgetfulness that man can ever reach the point of fancying himself to possess a "truth" of the grade just indicated. If he will not be satisfied with truth in the form of tautology, that is to say, if he will not be content with empty husks, then he will always exchange truths for illusions. What is a word? It is the copy in sound of a nerve stimulus.

His moral sentiment does not even make an attempt to prevent this, whereas there are supposed to be men who have stopped snoring through sheer will power.

They are deeply immersed in illusions and in dream images; their eyes merely glide over the surface of things and see "forms."
