  According to Rosmini, eclecticism, especially that upheld by Victor Cousin, is not the way to promote reconciliation between conclusions. Philosophical systems are not brought together as a result of arbitrary choice between what they offer. Each system, if it is truly such, will have a principle from which deductions are made, and will be able to be reconciled, despite accidental differences, with every other system sharing the same principle. On the other hand, systems will not be reconcilable, despite their accidental agreement, if their basic principles differ. In the former case, agreement will be possible by working back to the principle, and setting out once more from there; in the second case, apparent agreement will only be skin-deep. Only shared principles allow for effective reconciliation between systems.
