This is a valid statement with no fallacy. It follows the form of the valid logical argument known as the A-I proposition, which states that if all A are B, then some B are A. In this case, the A proposition is "Some poets are sensitive souls," and the contrapositive is "Some not-insensitive souls are not poets." Therefore, it is valid to conclude that "Some poets are not insensitive souls."
