The pioneer, the creator, the explorer is generally a single, lonely person rather than a group, struggling all alone with his inner conflicts, fears, defenses against arrogance and pride, even against paranoia. He has to be a courageous man, not afraid to stick his neck out, not afraid even to make mistakes, well aware that he is, as Polanyi has stressed, a kind of gambler who comes to tentative conclusions in the absence of facts and then spends some years trying to figure out if his hunch was correct. If he has any sense at all, he is of course scared of his own ideas, of his temerity, and is well aware that he is affirming what he cannot prove.
