I think he/she is trying to get at the point of whether or not there is an EXACT answer to anything. Well if that’s your question, then no. There is no exact answer to anything. Answers rely on the mind, which is 100% subjective.
Sorry, but there is no exact answer to 1+1=2 unless one specifies what 1 means. See Goethe. Mathematical identities only confirm mathematical identites, not human experience. Whoever can find a dividing line between subjective and objective thought, as if they are somehow polar opposites, please show it to me. Experience shows no such dissection. Humean, Cartesian ,Kantian, Fregean bifurcations of knower from known have been hotly contested by most philosophers since and may be the meat of contemporary philosophy. So, please, let’s not be atavistic.
