It is written in our nature that we are extreme beings; that is our force and the cause of our progress. We necessarily and instinctively fly to the utmost limits of our being. We do not feel ourselves to live and we are unable to organize a life that shall satisfy us, except upon the confines of our possibilities. Thanks to that self-enlightening instinct, there is a more and more unanimous tendency to stop no longer at intermediate solutions, to avoid henceforth all half-way experiments or at least to hurry through them as rapidly as possible. II This does not mean that our tendency towards extremes is enough to guide us to definite certainties. There are always two extremes between which we have to choose; and it is often difficult to decide which is the starting-point and which the final goal. In morals, for instance, we have to choose between absolute egotism or altruism and in politics between the best-organized government that it is possible to imagine, directing and protecting the smallest acts of our life, or the absence of all government. The two questions are still insoluble. Nevertheless, we are free to believe that absolute altruism is more extreme and nearer to our end than absolute egotism, in the same way as anarchy is more extreme and nearer to the perfection of our kind than the most minutely and irreproachably organized government, such as, for instance, one might imagine to prevail at the last limits of integral socialism. We are free to believe this, because absolute altruism and anarchy are the extreme forms that demand the most perfect man. Now it is towards perfect man that we must turn our gaze; for it is in that direction that we must hope that mankind is moving. Experience still shows that we risk less by keeping our eyes before us than by keeping them behind us, less by looking too high than by not looking high enough. All that we have obtained so far has been announced and, so to speak, called forth by those who were accused of looking too high. It is wise, therefore, when in doubt, to attach one's self to the extreme that implies the most perfect, the most noble and the most generous form of mankind. Thus it was that this reply could be given to one who asked whether it were well to grant to men, in spite of their present imperfections, the most complete possible liberty: "Yes, it is the duty of all whose thoughts go before the inconscient mass to destroy all that trammels the liberty of men, as if all men deserved to be free, even though we know that they will not deserve to be so until long after their deliverance. The harmonious use of liberty is acquired only by a long misuse of its benefits. By proceeding at the first to the most distant and highest ideal we have the greatest chance of afterwards discovering the best." And what is true of liberty is also true of the other rights of man.
