Estimating the IQs of Philosophers: Friedrich Nietzsche, Aristotle, Albert Camus, and Jean-Paul Sartre

Estimating the IQs of historical figures like philosophers is a fascinating but inherently speculative task. IQ testing is a relatively modern concept, and these great thinkers did not have the opportunity to take such tests during their lifetimes. Nevertheless, scholars and enthusiasts have attempted to gauge their intelligence based on their profound writings, ideas, and contributions to philosophy.

Friedrich Nietzsche

Friedrich Nietzsche is often regarded as a profound thinker with a deep and complex understanding of human existence. Some estimates place his IQ in the range of 140-160, reflecting his ability to produce sophisticated and penetrating works of literature and philosophy. His intricate ideas and literary style suggest a high level of intelligence, making him a challenging and influential figure in the philosophical landscape.

Aristotle

As one of the most influential philosophers in Western thought, Aristotle's intellectual contributions span numerous fields, including metaphysics, ethics, logic, and politics. His analytical and systematic approach to knowledge is a hallmark of his work. Estimates of his IQ might also fall in the 140-160 range, reflecting his profound impact on human understanding and his extensive knowledge.

Albert Camus

Albert Camus is known for his existential and absurdist philosophy. Some estimates suggest his IQ may have been around 120-140, reflecting his unique insights into the human condition. However, these numbers are highly speculative and should be taken with caution. Nonetheless, Camus's ability to articulate profound existential questions has made him a seminal figure in modern Western philosophy.

Jean-Paul Sartre

Jean-Paul Sartre is a key figure in existentialism and is often considered highly intelligent. Speculative IQ estimates for Sartre range from 130-150. Sartre's deep exploration of existential themes and his philosophical contributions have made him a pivotal figure in 20th-century thought.

The Rarity of High IQs

Measuring intellectual rarity through past IQ estimates is a complex issue. When considering IQ as a measure of extreme intelligence, it's worth noting that highly intelligent individuals like Nietzsche, Camus, and Sartre would place them in the top 1% or even the top 10% of their respective populations. If we consider highly unusual cases like a 175 IQ, we might place figures such as Kant, Goethe, and possibly Gauss in the category of the very few smartest individuals in recorded history.

Personal Insights and Bias

My personal estimates, which are biased by my reading experience of mostly German philosophy, include:

145-160 IQ: Karl Marx (for applying Hegel's ideas effectively) 160 IQ: Friedrich Nietzsche (for sometimes "copying" from Kant, but producing complex thought) 175 IQ: Immanuel Kant (for his profound contributions and arguably Leibniz and Johann Wolfgang von Goethe)

It's important to note that these estimates are subjective and based on my personal interpretations of their intellectual legacies. These figures stand out in their respective eras and have left indelible marks on philosophy and human understanding.
