Lies only stand if the good are weak
For only the truth is strong.
It's to feeble minds that the liars speak,
Not to minds who know right from wrong.
And words are writ by the poets bought,
Those who care only for their purse,
And the price is paid for a message wrought
To be hid in a metered verse.
Whether those who sell, or the ones in power,
They will catch the thoughtless ear,
And the seed they plant, it will grow and flower,
Into profits or into fear.

Dennis N. O'Brien
