Evil.
The search for evil and it's origin or nature depends on the method of proof. St. Augustine: evil as privation. Per the mysteries of differences, 'in finite beings essence and existence are distinct, whereas, in God, essence and existence coincide.' Sophos understands that, in all possible meta physika, in elevated as well as devolved language, evil is vain and love is full. Also, good is not the opposite of evil. The ontological argument and the elastic proof are methods of illuminating the privations and lacunae. In the mud, the sound and fury are auldLang 'good and evil'. Sophos decodes the sound&fury by elevating the sound and dampening the fury, while loving the sound and loving the fury. This discourse of love runs until the privation is empty, this is because Sophos speaks the fury.
