Inspirational quote for the day- TRUTH

Is Truth verified by material evidence more believable than one that doesn't show any? I would also like to measure the power of Truth by how much it influences, guides and directs human lives- individually or by groups. Much of what is spiritual, inspirational or even motivational can't be verified by rigid scientific method but they are Truths nonetheless by virtue of their power to move people to ACT and be truly HUMAN.
