One thing that being a scientist has taught me is that you can never be certain about anything. You never know the truth. You can only approach it and hope to get a bit nearer to it each time. You iterate towards the truth. You don't know it.
He that desireth to acquire any art or science seeketh first those means by which that art or science is obtained. If we ought to do so in things natural and earthly how much more then in spiritual?
