I will no longer argue with the senseless and unreasonable; for they are void of reason and common sense.

Sometimes I think humans have a common sense that completely defies logic.

In contrast to logic, there is common sense, or still better, the Spirit of Reasonableness.

Science is simply common sense at its best - that is, rigidly accurate in observation, and merciless to fallacy in logic

TO ALL MANKIND

Speak kind words
to mankind
and the unkind
will attack you.

Speak common sense
using any of your senses,
and you will be attacked by
the senseless.

Speak truth,
and you will be attacked by
the untruthful.

Speak about absolutely nothing,
and absolutely nothing
will speak back,
but then nothing at all
will ever change.

I mean, you could claim that anything's real if the only basis for believing in it is that nobody's proved it doesn't exist!
