доводы "за" и "против"; см. тж. pro and con

At length the lady of the caravan shook off her fit of meditation, summoning the driver to come under the window at which she was seated, held a long conversation with him in a low tone of voice as if she were asking his advice on an important matter, and discussing the pros and cons of some very weighty matter. (Ch. Dickens, ‘The Old Curiosity Shop’, part I, ch.

He would weight the pros and cons of an issue until his aides were in despair, then make up his mind and never waver again. (F. Knebel and Ch. Bailey, ‘Seven Days in May’, ‘Monday’) — Приводя в отчаяние своих помощников, он долго взвешивал все за и против, но, приняв решение, уже никогда от него не отступал.
