"[C]ultivated risk-taking represents an 'experiment with trust' (in the sense of basic trust) which consequently has implications for an individual's self-identity. (...) In cultivated risk-taking, the encounter with danger and its resolution are bound up in the same activity, whereas in other consequential settings the payoff of chosen strategies may not be seen for years afterwards."

Any attempt to shape the world and modify human personality in order to create a self-chosen pattern of life involves many unknown consequences. Human destiny is bound to remain a gamble, because at some unpredictable time and in some unforeseeable manner nature will strike back. The multiplicity of determinants which affect biological systems limits the power of the experimental method to predict their trends and behavior.
