Knowing the truth is possible but being certain of the truth is not possible. Certainty is a luxury of the ignorant. There is an argument that can be made against the existence or presence or activity or feeling of about anything. Claiming certainty is possible only for those who ignore some or all of the facts. What is truth? Well, that depends on who you are, where you come from, how you were raised, etc. there is not one truth that is superior to all other truths. That’s ridiculous. The only thing certain about truth is that truth is not certain. It must be accepted by a leap of faith.
