It is indeed the boundary of life, beyond which we are not to pass; which the law of nature has pitched for a limit not to be exceeded.

The honor we receive from those that fear us, is not honor; those respects are paid to royalty and not to me.

Even opinion is of force enough to make itself to be espoused at the expense of life.

The finest lives in my opinion are the common model, without miracle and without extravagance.

Nature is a gentle guide, but not more sweet and gentle than prudent and just.
