Its appearance, however, will cease to be wonderful, and its real significance will become more apparent, if we consider the class of thinkers who have elaborated and popularised it. They have been men and women, for the most part, who have had the following characteristics in common. Their early training has been religious;[28] their temperaments have been naturally grave and earnest; they have had few strong passions; they have been brought up knowing little of what is commonly called the world; their intellects have been vigorous and active; and finally they have rejected in maturity the religion by which all their thoughts have been coloured. The result has been this. The death of their religion has left a quantity of moral emotions without an object; and this disorder of the moral emotions has left their mental energies without a leader. A new object instantly becomes a necessity. They are ethical Don Quixotes in want of a Dulcinea; the best they can find is happiness and the progress of Humanity; and to this their imagination soon gives the requisite glow. Their strong intellects, their activity, and their literary culture each supplements the power that it undoubtedly does give, with a sense of knowing the world that is altogether fictitious. They imagine that their own narrow lives, their own feeble temptations, and their own exceptional ambitions represent the universal elements of human life and character; and they thus expect that an object which has really been but the creature of an impulse in themselves, will be the creator of a like impulse in others; and that in the case of others, it will revolutionise the whole natural character, whereas it has only been a symbol of it in their own.
