I'd say I'm not forced to believe there is a table, I'd say I accept there is a table there based upon my observations. If you tell me that you saw an elephant at the circus then I will accept my perception of you telling me this and I will probably accept that my perception of you telling me you saw an elephant at the circus is a suitable substitute for my own direct observations. That is, I will believe you. However if you told me you saw an elephant at the circus that could fly by flapping its ears then I probably wouldn't accept my perception of you telling me you saw an elephant that could fly by flapping its ears as a suitable stand in for my own direct observations and I wouldn't believe you.
