Every attitude towards life has a re-echo, and the attitude is formed by expectation. When one expects one's fellow-man to love one, his fellow-man does love him, and when one expects harm from another, then harm comes. When a person is afraid of a dog, he gives the dog a tendency to bite him. This can be noticed so plainly in the lower creation, that every animal is afraid for another animal, and the expectation of harm makes it fear more than does the idea of the hugeness of the form or the bodily strength of another animal.
