Dualism assumes that the gulf between the two empires, the thinking and feeling on one side and the not-thinking and not-feeling on the other side, is insurmountable; Monism however maintains that there is no gulf, for there is no reason for such an assumption. Both realms, the feeling and thinking on the one hand, and the unfeeling and unthinking on the other hand, are not at all distinct and separate provinces. The transition from the one to the other takes place by degrees, and there is no boundary line between them. The atoms of oxygen which we inhale at present are not engaged in any action that is accompanied with feeling, but some of them will be very soon active in the generation of our best thought accompanied with most intense consciousness. After that they are thrown aside in the organism and pass out as waste products in the shape of carbonic acid. #Telepathy.# The spiritual originates from and disappears into the non-spiritual not otherwise than light originates out of, and dissolves again into, darkness. Light is usually considered as the emblem of mind, for light also discloses to our eye those objects which are so far away that we can never expect to touch them with our hands. So mind, the representation of the objective world in feeling substance, unveils the riddles of the universe and shows the secret connections of most distant things and events. Spiritualists discuss with great enthusiasm the problem of telepathy. Telepathy means "far-feeling." Mental activity exhibits in all its elements instances of telepathy in the literal sense of the word. We do not feel our sense-organs; but in and through our sense-organs objects outside of us are felt. In and through our eyes most distant stars are seen. If telepathy has no other but its natural and proper meaning we must confess that the whole activity of the mind rests upon telepathy. However, we cannot recognise telepathy in the sense in which the word is often employed by spiritualists. With many it denotes a process of such far-feeling as is not caused in the natural way and as stands in contradiction to the mechanical interconnection of causes and effects in the universe. It is supposed to supersede the order of nature. We recognise telepathy fully in the sense that feelings represent distant events and that mind can thus penetrate into the remotest regions of time and space, but not in any other sense that stands in contradiction with the universal order of mechanical causation.
