PET. If he says black’s black—if I have a humour to say ’tis blue—let that pass—all’s one for that. If I have a humour to prove it, it must be granted.

WIT. Not positively must. But it may; it may.

PET. Yes, it positively must, upon proof positive.

WIT. Ay, upon proof positive it must; but upon proof presumptive it only may. That’s a logical distinction now, madam.

MRS. MAR. I perceive your debates are of importance, and very learnedly handled.

PET. Importance is one thing and learning’s another; but a debate’s a debate, that I assert.

WIT. Petulant’s an enemy to learning; he relies altogether on his parts.

PET. No, I’m no enemy to learning; it hurts not me.

MRS. MAR. That’s a sign, indeed, it’s no enemy to you.

PET. No, no, it’s no enemy to anybody but them that have it.
