" So the conservative who resists change is as valuable as the radical who proposes it -- perhaps as much more as the roots are more vital than grafts. It is good that new ideas should be heard, for the sake of the few that can be used; but it is also good that new ideas should be compelled to go through the mill of objection, opposition, and contumely; this is the trial heat which innovations must survive before being allowed to enter the human race. It is good that the old should resist the young, and that the young should prod the old; out of this tension, as out of the strife of the sexes and the classes, comes a creative tensile strength, a stimulated development, a secret and basic unity and movement of the whole. "
" Just as a balloon filled gradually with air bursts when the limit of its tensile strength is passed, there are thresholds of radical, disruptive change in politics. When those thresholds are crossed, the impossible suddenly becomes probable, with revolutionary implications for governments and nations. "
" Some spider silks are really strong, but not all of them are. The ones that are really strong can actually rival steel and approach the tensile strength of Kevlar. Thus far, the dragline silk seems to be the strongest. "
