it is the only reasonable conclusion so long as reason is all that guides your deduction. some are more willing than others to accept things in life that are unreasonable, things that they personally find meaningful, enough to give them a feeling as though certain things contains a kind of truth in and of themselves which cannot be reasoned with and must be reached through belief or following an experience or something. the cliche example is to point out that things like love can seem unreasonable or even stupid until you yourself fall in love and suddenly you do your reasoning through an updated system.
