Activities that pose risks to life are acceptable if and only if each person who bears the risks either gains some net benefit that cannot be had without such risks, or bears the risks voluntarily.
Summary
“if and only if” makes the principle a biconditional relationship. This means if one side of the relationship is true, the other must be true as well. And if one side is false, the other must be false.
