Right, but those are merely conceptual ideas. They exist only as concepts within minds, not as actual things that exist independent of whether or not minds are actually around to think about them.
Do they all need a mind? Do you think that in all possible worlds (including those without minds) that if P then Q; P therefore Q would not be the case? Most think that the applicability of mathematics would exists even if a mind never contemplated them.
Your real conundrum will be that your sole source of knowledge, science, presupposes logic, mathematics, and philosophy. If it presupposes them, where did they come from? If you say science somehow validates them, that would be question-begging. Even if you can't figure that out, the fact that science says they exists give us a clear case for their independent existence.
