I did not say "Logic is not a positive science."
I also said no such thing before so don't know where you get your "again" from????
I said you should not be applying positive science methodology to normative sciences.
Those facts aren't facts as you claim them. You forgot to mention the qualifying statement if all else remains the same, but sadly unlike in positive sciences, all things do not stay the same.
For example confidence is a big factor which along with the economic climate and job security determines whether people will bring their purchase decisions forward or postpone them.
This is why despite historic low interest rates not much investment going on. All that old stuff that monetarists like to shout about controlling the Ms by varying interest rates to influence inflation is not what its cut out to be.
I said logic is not a positive science. Positive sciences and normative sciences are both based in logic.
I know that you do not like logic as evidenced by any of your posts, which lack it.
you just said the same thing. Logic is not a positive science. Positive sciences and normative sciences are based upon propositional and predicate logic. A: Positive economics is objective and fact based, while normative economics is subjective and value based. Positive economic statements do not have to be correct, but they must be able to be tested and proved or disproved.
Simply being a normative science does not preclude the use of logic. You are equivocating the meaning of proof. Do not confuse soundness with validity.
