"But it is not enough to desire something; if one really wants it adequate means must be used to secure it. And these means are not arbitrary, but instead cannot but be conditioned by the ends we aspire to and by the circumstances in which the struggle takes place, for if we ignore the choice of means we would achieve other ends, possibly diametrically opposed to those we aspire to, and this would be the obvious and inevitable consequence of our choice of means. Whoever sets out on the highroad and takes a wrong turning does not go where he intends to go but where the road leads him."
