In the theory of finance, and perhaps its practise, one often encounters the term, 'risk appetite', with the implication that since 'nothing ventured, nothing gained' the more one is willing to put at risk, the more one ultimately stands to gain. It is perhaps a worldly version of Christ's "whosoever will lose his life for my sake shall find it." The term, then, is not quite accurate since one could feed a pure risk appetite at a casino and be sure of ultimate ruin. You are to venture, to take on risk, only when there is good reason to believe that the odds are there to be beaten. In the theory of life the equivalent may be 'truth appetite'; how much of this commodity that mankind can bear so little of can you take? There may even be a casino of debased truths, but there are certainly truths it's worth losing your life for, you know, that kind that set you free.
