To understand things we must have been once in them and then have come out of them; so that first there must be captivity and then deliverance, illusion followed by disillusion, enthusiasm by disappointment. He who is still under the spell, and he who has never felt the spell, are equally incompetent. We only know well what we have first believed, then judged. To understand we must be free, yet not have been always free.

Henri Amiel (1821 – 1881)
