“A good statesman, like any other sensible human being, learns more from his opponents than from his fervent supporters. For his supporters will push him to disaster unless his opponents show him where the dangers are. So if he is wise he will often pray to be delivered from his friends, because they will ruin him. But, though it hurts, he ought also to pray never to be left without opponents; for they keep him on the path of reason and good sense. The national unity of free people depends upon a sufficiently even balance of political power to make it impracticable for the administration to be
arbitrary and for opposition to be revolutionary and irreconcilable.

With reference to the above passage, the following assumptions have been made :
I. In a democracy, a strong opposition is required only if the Head of Government is indifferent.
II. The more aggressive the opposition, the better is the governance in a democracy.
