Ivan Illich is often regarded as a pioneer in promoting the use of bicycles as a means of transportation. As early as 1973, the philosopher and writer Ivan Illich foresaw a growing conflict between bicycles and motor vehicles, predicting a "fierce battle between bicycles and engines." In a time when industrial societies seemed increasingly complex and overwhelming, Illich's works offered a clear and thought-provoking perspective. His ideas, often centered around the concept of degrowth, do not advocate for economic decline but instead emphasize the need for personal and societal autonomy. Illich believed that people should free themselves from the pressures of constant productivity and their reliance on technology. He was one of the first to highlight the potential downsides of industrial society, and this year would have marked his 100th birthday. To honor his legacy, a conference is being held from May 27 to May 29 at the Campus Condorcet Paris-Aubervilliers. Meanwhile, in the realm of public health, a government decision has sparked significant debate. The number of mandatory vaccines for children is set to increase from three to eleven by 2018. This move has raised questions about individual choice, public health, and the role of the state in personal decisions. At the same time, home schooling is gaining more attention as an alternative to traditional education. Anthony and Nathalie Vandeuren, despite their demanding careers, have chosen to educate their two children at home. This decision reflects a growing trend among families seeking more control over their children’s learning experiences. Ivan Illich, who was once a Roman Catholic priest, was known for his critical views on the misuse of reason without a moral framework. His early career as a priest may have influenced his later critiques of modern society, making him one of the most relevant thinkers on the challenges of contemporary life. Illich lived a life that reflected his ideas, embracing simplicity and questioning the structures that dominate modern existence. He was not only a philosopher but also a chemist and a critic of industrial society, consistently aligning his personal life with his intellectual pursuits. His work continues to inspire discussions about the balance between technology, autonomy, and the ethical dimensions of modern living.
