The Enhancement of Human Cognitive Ability to Imagination, Inspiration and Intuition
So you must say to yourself, through your physical organism you - as I said, always with the exception of the eyes - do not stop the sensory impressions. But you do not keep thoughts out either. And you can even imagine - it remains hypothetical for the time being for external observation - that even if there is a relative calm during the night for certain senses due to the social facilities, it is certainly not present for other senses; certainly not for the sense of warmth and cold, for example, and certainly not for the sense of touch either, because, isn't it true, when you press your thumb on the blackboard, you perceive the pressure. Why should the perception of pressure not be the case when you lay your back on the bed? You must of course perceive this pressure, which is conveyed by the sense of touch, throughout the night. Likewise, if you place something on your hand, you will feel it. Why shouldn't you be aware of the comforter you put on yourself throughout the night and so on? But not only that, but the continuation inwards, the formation of ideas and thoughts, why should we stop at them? Because they are mediated by the organism.
