"A subtle thought that is in error may yet give rise to fruitful inquiry that can establish truths of great value"
About this Quote
The line also carries the quiet ethos of mid-century scientific humanism, the worldview that treated knowledge as a self-correcting machine powered by curiosity rather than certainty. Asimov, a scientist and a career explainer, is defending the messy backstage of progress against the polished myth of genius. We tend to celebrate breakthroughs as clean, inevitable revelations; he points to the false starts as the real engine room. Error isn't an embarrassment in this framing, it's a tool.
There's an implied argument here about how inquiry should be organized: institutions, classrooms, and public debates should reward hypotheses that can fail productively. That has bite in a culture that often treats being wrong as moral weakness, especially in public. Asimov is asking for a politics of epistemic humility: judge ideas not only by whether they're correct today, but by whether they force better questions, tighter experiments, clearer definitions.
It works because it flatters rigor without sanctifying certainty. Truth, in Asimov's telling, isn't the opposite of error; it's what error, properly handled, can eventually buy you.
