We noticed that this external search lands us in a failure, finally, because of the simple reason that the things we see are outside of us. A thing that is really outside cannot come in contact with us, because we have already dubbed it as an outsider . A thing that is external to us cannot become a part of our knowledge. It is an assimilation of the object into the consciousness. If I assimilate you in my consciousness, I know you, but if you stand outside as a stranger to me, as an object which is totally independent of me, I cannot know you.
All knowledge is participation in the content thereof.
I cannot know you and you cannot know me. This is what has happened to the scientific observations of modern times. If science is an observation of objects, regarding them as objects having nothing to do with the subjects which observe them, then, science cannot give us knowledge. It can only give us descriptive information, the length and the breadth, the weight and the mass, the form and the colour, etc., of an object. I cannot know you, even if I know your height and weight, your girth, colour, shape, geometrical feature, or the chemical structure of your body.
