I see what you mean but I suggest that you are wrong. The outcome of reasoning is the result of what one has taken into consideration, what one has rejected and accepted. If we ask a dozen people to consider a question, the answers given will not all be the same. They will depend on intelligence, how well one is informed, one's life experience and a host of other subjective factors. Thus, I cannot claim that my reasoning is objective. You are overlooking the fact that in reasoning you are not necessarily starting from the same place as others. Hence, your reasoning can only be subjective.
