TL;DR
Recent analysis shows Isaac Newton’s extensive writings were predominantly religious and alchemical, with only a minority dedicated to science. This reshapes understanding of his work and legacy.
Recent scholarly analysis confirms that only about 3 million of Isaac Newton’s estimated 10 million words were dedicated to scientific work, with the majority focused on religious, alchemical, and personal subjects.
Research conducted by Sarah Dry, author of ‘The Newton Papers,’ and recent efforts by The Newton Project, reveal that Newton’s writings were heavily dominated by religious and alchemical texts. Of the approximately 10 million words Newton left behind, roughly half are religious, about 1 million are alchemical, and only around 3 million pertain to his scientific and mathematical work.
These findings emerged from the analysis of Newton’s extensive unpublished papers, which were largely chaotic and unorganized until they were cataloged and transcribed in recent decades. Historically, Newton’s religious and alchemical writings were kept private due to fears they could damage his reputation, especially given the heretical nature of some views, such as his rejection of the Holy Trinity.
Experts note that the focus on religious and alchemical texts was not due to a conspiracy but was rooted in the social and personal context of Newton’s time. The papers include complex technical content, making them difficult to interpret and often discouraging for early editors and catalogers.
Why It Matters
This discovery alters the common perception of Newton as primarily a scientist and mathematician. It highlights that his intellectual pursuits were much broader and more diverse than traditionally acknowledged, involving extensive religious and alchemical studies. For modern readers and scholars, understanding the scope of his writings provides a more nuanced view of his character and intellectual life.
Moreover, this revelation underscores how historical figures’ legacies can be shaped by selective publication and interpretation. Newton’s reputation as a scientific pioneer remains intact, but recognizing his broader interests may influence how his work is contextualized within history and science.

Background
Isaac Newton’s writings have been largely inaccessible until recent decades due to their chaotic state and the sensitive nature of some content. The Newton Project, a non-profit organization, has been working to transcribe and publish all of Newton’s papers, making them available online. Historically, only a fraction of his work was published or widely known, with much of it kept hidden due to fears of heresy or damage to his reputation.
Earlier biographers, such as David Brewster in the Victorian era, acknowledged the presence of heretical and alchemical texts but emphasized Newton’s scientific achievements. It was only in the 1960s that many of his papers were more widely studied, revealing the full extent of his diverse interests. The recent analysis confirms that the majority of his writings were not scientific but religious and alchemical in nature.

Key Questions
Fears that his heretical religious views and alchemical writings could damage his reputation led to the papers being kept private or suppressed until recent decades.
Does this change how we view Newton’s scientific achievements?
While it broadens understanding of his interests, Newton’s scientific work remains highly influential. The discovery adds context but does not diminish his contributions to physics and mathematics.
What is the significance of the religious and alchemical writings?
They reveal a more complex and multifaceted thinker, whose pursuits extended beyond the scientific realm into theology and mysticism, reflecting the intellectual environment of his era.
Will all of Newton’s papers eventually be published?
The Newton Project continues to work on transcribing and publishing his remaining writings, but the process is ongoing and may take years to complete fully.
