The divide-and-rule strategy is invaluable in trying to influence people verbally. Start by seeming to take your opponents’ side on some issue, occupying their flank. Once there, however, create doubt about some part of their argument, tweaking and diverting it a bit. This will lower their resistance and maybe create a little inner conflict about a cherished idea or belief. That conflict will weaken them, making them vulnerable to further suggestion and guidance.
