Synthesized answer
Berlin emphasizes the *ongoing* challenge posed by historical dissenters because their thinking "still challenges conventional wisdom" [1]. This highlights the lasting impact of these original minds and their ability to question established beliefs even today.
This ongoing challenge implies that conventional wisdom is not static or necessarily correct. The fact that these thinkers "swam against the current of their times" suggests that they offered alternative perspectives that, over time, prove to be enduring and relevant [1]. Their continued ability to challenge indicates a fundamental characteristic of conventional wisdom: it is susceptible to critique and can be overturned or modified by dissenting ideas.

From the book
Title: Against the Current by Isaiah Berlin Description: Berlin's main theme in these essays is the importance in the history of ideas of dissenters whose thinking still challenges conventional wisdom - among them Machiavelli, Vico, Montesquieu, Herzen and Sorel. With his unusual powers of imaginative re-creation, he brings to life original minds that swam against the current of their times, and in the process offers a powerful defence of variety in our visions of life. Roger Hausheer's introduction surveys Berlin's whole oeuvre, and the full bibliography of his pubication has been updated…
More questions about this book
- How would you explain Berlin's core argument about the "importance in the history of ideas of dissenters" to a high school student, using an analogy that makes the concept of "conventional wisdom" clear?
- The text mentions Berlin's "unusual powers of imaginative re-creation." How might this skill be crucial for understanding thinkers who "swam against the current," compared to a purely factual historical account?
- If Berlin is offering a "powerful defence of variety in our visions of life," how does the study of historical dissenters directly support this defense, and what are the potential downsides if such variety is not valued?
- What criteria might Berlin use to distinguish between a "dissenter whose thinking challenges conventional wisdom" and merely someone who held an unpopular opinion at the time?
