The family is an early expedient and in many ways irrational. If the race had developed a special sexless class to be nurses, pedagogues, and slaves, like the workers among ants and bees, then the family would have been unnecessary. Such a division of labor would doubtless have involved evils of its own, but it would have obviated some drags and vexations proper to the family.

Imagination is potentially infinite. Though actually we are limited to the types of experience for which we possess organs, those organs are somewhat plastic. Opportunity will change their scope and even their center.

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.

Docility is the observable half of reason.

There is nothing sweeter than to be sympathized with.
