Using Your Own Judgement
From "We Exist! Why?" by Elizabeth Young

"Believing in someone else's beliefs does not make them your own beliefs. Beliefs become ours when we investigate the evidence put before us and then become convinced. If there is a shadow of doubt, then we cannot believe. We can be convinced by lies just as well as we can by the truth. We can also fall into error when we put our confidence in others who merely appear to know the truth. It is for us to use our own judgement.
Even those who do know can get it wrong sometimes. I once, in conversation placed value on a piece of fabric that I mistook for pure silk. The person I was speaking to corrected me, saying it was a man made fibre. I insisted it was silk. My words were accepted and I was sure I was right. I realised later that week, after working closely with the fabric and seeing its behaviour, that is was indeed a man made fibre.
I had not set out to deceive but I had succeeded in giving my belief as the truth. It was taken for granted that because I worked with fabrics I had to be right.
There are times when we lose confidence in the truth in the presence of so called experts. If we have evidence and know that we are right, it is enough, it is enough to stay true to what we know. Opinions and expertise count for nothing when we know for sure."
