The main point in the philosophy of Fichte was a statement that sounds at first sight rather strange. "The whole world - it is I" This provision, of course, should not be taken literally. Recall that the basic idea of ??Hume was the thesis: "The whole world - the totality of my feelings," which we also considered not literally, but in the sense that the external reality is given to us through the senses, and what it is in itself - is unknown. However, the philosophy still was such a rare view, according to which it is believed that the whole world - this is just my feeling, that is no reality there, but only I exist, yet, I observed outside - these are my feelings, illusions, fictions, like dream images. I am, and there is no peace at all.
