Beware the barrenness of a busy life.

The warm love has the coldest end.

We are in fact convinced that if we are ever to have pure knowledge of anything, we must get rid of the body and contemplate things by themselves with the soul by itself. It seems, to judge from the argument, that the wisdom which we desire and upon which we profess to have set our hearts will be attainable only when we are dead and not in our lifetime.

In every sort of danger there are various ways of winning through, if one is ready to do and say anything whatever.

A man should inure himself to voluntary labor, and not give up to indulgence and pleasure, as they beget no good constitution of body nor knowledge of mind.

If we pursue our habit of eating animals, and if our neighbour follows a similar path, will we need to go to war against our neighbour to secure greater pasturage, because ours will not be enough to sustain us, and our neighbour will have a similar need to wage war on us for the same reason.

Our lives are but specks of dust falling through the fingers of time. Like sands of the hourglass, so are the days of our lives.
