In "Middlemarch," George Eliot suggests that those in opposition can always find reasons to challenge ideas or decisions. Their objections can stem from an endless supply of unwarranted doubts, allowing them to undermine arguments without needing substantial evidence. This highlights how criticism can often be based on speculation rather than fact.

Opponents can leverage a limitless array of objections, drawing not only from established knowledge but also from the uncertainties and ignorance surrounding a topic. This dynamic shows the power of dissenting voices, which can obscure clear thinking and stall progress by introducing confusion and fear rather than constructive dialogue.
