2 If you wish to fear nothing, think that every- 

 thing is to be feared ; consider by how slight 

 causes our life is dissipated. Neither food nor 

 drink, nor waking nor sleeping, is healthful, except 

 in due measure. One may soon realise that 

 we are but puny, insignificant bodies, weak and 

 unstable, that small effort is needed to compass our 

 destruction. The only sufficiency of danger, doubt- 

 less, would be the earth's trembling, its sudden

 solace of death greater than the very liability to 

 death, no solace of all the terrors from without equal 

 to the thought that there are countless dangers 

 within our own bosom. What greater madness than 

 to collapse at the sound of thunder, and through 

 fear of lightning to creep under the ground ? What
