Whether the character of one Order necessarily presupposes the character of another Order?

❌ Objection 1 : It would seem that the character of one Order necessarily presupposes the character of another Order. For there is more in common between one Order and another, than between Order and another sacrament. But the character of Order presupposes the character of another sacrament, namely Baptism. Much more therefore does the character of one Order presuppose the character of another.

❌ Objection 2 : Further, the Orders are degrees of a kind. Now no one can reach a further degree, unless he first mount the previous degree. Therefore no one can receive the character of a subsequent Order unless he has first received the preceding Order.
