In fact the whole point of necessary truths is that they are necessarily true. They cannot be false in the absence of a conscious mind because - by definition - they cannot be false under any circumstances. If your argument denies this , then your argument is wrong.
This is a very good point.
If necessary truths are dependent on something, then they are not necessary in themselves. 'Dependent' means that the absence of something - in this case mind- makes a difference for things that depend on it. This refutes the necessity of MrQ's necessary truths, since he defines them as being dependent on a conscious mind.
In a universe with only a cube and a sphere the question of how many things there are can neither be asked nor answered, unless the cube is talking to the sphere.
