The happiest people I have known have been those who gave themselves no concern about their own souls, but did their uttermost to mitigate the miseries of others.

My religious superstition gave place to rational ideas based on scientific facts, and in proportion as I looked at everything from a new standpoint, I grew more happy day by day.

Whether our feet are compressed in iron shoes, our faces hidden with veils and masks; whether yoked with cows to draw the plow through its furrows, or classed with idiots, lunatics and criminals in the laws and constitutions of the State, the principle is the same; for the humiliations of the spirit are as real as the visible badges of servitude.

No mortal ever has been, no mortal ever will be like the soul just launched on the sea of life.

I can truly say, after an experience of seventy years, that all the cares and anxieties, the trials and disappointments of my whole life, are light, when balanced with my sufferings in childhood and youth from the theological dogmas which I sincerely believed. . . . The memory of my own suffering has prevented me from ever shadowing one young soul with the superstitions of the Christian religion.

I can say that the happiest period of my life has been since I emerged from the shadows and superstitions of the old theologies, relieved from all gloomy apprehensions of the future, satisfied that as my labors and capacities were limited to this sphere of action, I was responsible for nothing beyond my horizon, as I could neither understand nor change the condition of the unknown world. Giving ourselves, then, no trouble about the future, let us make the most of the present, and fill up our lives with earnest work here.

Self-development is a higher duty than self-sacrifice.
