W. Why, then, dost thou refuse to answer my question?

T. Because I will not.

W. But why will you not?

T. Then, thou wouldst claim an exception to my cause.

W. I claim only consistency.

T. Am I inconsistent?

W. When thou wilt answer as thou knowest, thou art consistent; but when thou seest not what is true, thou mayest be inconsistent with truth. Thou wilt not say thou art consistent in all things.

T. Who art thou?

W. I am thy friend.

T. How may I know thee to be my friend?
