Conscience:
I'll not meddle with it,
it is a dangerous thing,
it makes a man a coward;
a man cannot steal,
but it accuseth him;
a man cannot swear,
but it checks him;
a man cannot lie with his neighbour's wife,
but it detects him:
'tis a blushing shame-faced spirit,
that mutinies in a man's bosom;
it fills one full of obstacles:
it made me once restore a purse of gold,
that I found;
it beggars any man that keeps it:
it is turned out of all towns and cities for a dangerous thing;
and every man that means to live well,
endeavours to trust to himself,
and live without it.
[Richard III]
