Culture is on the horns of this dilemma: if profound and noble it must remain rare, if common it must become mean.

...science is nothing but developed perception, interpreted intent, common-sense rounded out and minutely articulated. It is therefore as much an instinctive product, as much a stepping forth of human courage in the dark, as is any inevitable dream or impulsive action.

Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement: and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it. In the first stage of life the mind is frivolous and easily distracted; it misses progress by failing in consecutiveness and persistence. This is the condition of children and barbarians, in which instinct has learned nothing from experience.

Eternal vigilance is the price of knowledge.

Never build your emotional life on the weaknesses of others.

Christianity persecuted, tortured, and burned. Like a hound it tracked the very scent of heresy. It kindled wars, and nursed furious hatreds and ambitions. It sanctified, quite like Mohammedism, extermination and tyranny. All this would have been impossible if, like Buddhism, it had looked only for peace and the liberation of souls. It looked beyond; it dreamt of infinite blisses and crowns it should be crowned with before an electrified universe and an applauding God... Buddhism had tried to quiet a sick world with anesthetics; Christianity sought to purge it with fire.

The traveller must be somebody and come from somewhere, so that his definite character and moral traditions may supply an organ and a point of comparison for his observations.
