If we observe
        carefully, there are two kinds of certainties in us
        which, although they have the same name, are deeply
        different one from the other. The first kind we
        get from a knowledge of a deterministic and well definite
        nature, which is usually attained during some
        experiences. Such certainty refers to something easily
        identifiable and does not play a particularly relevant
        role in our ways of being. The other kind of
        certainty, instead, is of esoteric nature and belongs to our
        interiority: suddenly it reveals itself and is inside us,
        without explanations. It does not depend on our wishes.
        We recognize it immediately and from that moment on it
        lives in us. It represents a force. However, man is particularly clever at fooling himself. He often flatters himself that he can turn into a certainty something which represents instead just a projection of a non esoteric wish.  |
