The I Index

The New York Times Book Review
Eilenberger is an energetic guide to these philosophers’ ideas, though it’s clear that he holds Weil’s writings in special esteem..
Caroline Moorehead,
The Guardian (UK)
In his enjoyable book, Eilenberger manages to convey not only his characters’ complicated lives but the convoluted flow of their endlessly agitated minds.
Stuart Jeffries,
The Observer (UK)
The Visionaries is much better than Eilenberger’s previous group biography.
Laura Hackett,
The Times (UK)
Ambitious, enthralling.
Lyndsey Stonebridge,
The Financial Times
This is where the significance of Eilenberger’s story really lies. Not one of these women was defending existing freedoms, because not one of them had ever been able to take freedom for granted in the first place.

Kirkus
While never quite providing a cohesive rationale for joining these four disparate writers together, Eilenberger offers solid insight into a center-minded way of thinking applicable to each.
