There are so many ways to get into this topic; Homeopathy, Astrology, Feng Shui, Alien Abductions, Seances and so on ad nauseum but let's pick a simple one - mathematics.
Do you accept the undeniable logic that 1+1 must ALWAYS equal 2?
I do. I cannot conceive of a situation where 1+1=3 but there was a time when I did! I would dismiss the undeniable logic of even simple mathematics to preserve the belief that the sum of the parts could be greater than the whole!
That was when I had faith. My old faith required me to accept that thousands of hungry people could be fed with a few loaves and fishes and that the leftover fragments would total more than the original amount. The undeniable beauty and simplicity of logic insists that this is impossible - it didn't happen.
Perhaps not all faith defies logic, (in which case is it really faith at all?) but the faith that contradicts proven, common-sense, undeniable logic surely needs to be respectfully retired.
