Courage ought to be guided by skill, and skill armed by courage. Neither should hardiness darken wit, nor wit cool hardiness. Be valiant as men despising death, but confident as unwonted to be overcome.
Philip SidneyThere is nothing sooner overthrows a weak head than opinion by authority, like too strong a liquor for a frail glass.
Philip SidneyAs in labor, the more one doth exercise, the more one is enabled to do, strength growing upon work; so with the use of suffering, men's minds get the habit of suffering, and all fears and terrors are not to them but as a summons to battle, whereof they know beforehand they shall come off victorious.
Philip Sidney
