His ideas were met with skepticism by his contemporaries, who were dominated by established philosophical views. Reid's lectures at the University of Aberdeen challenged the status quo, paving the way for future philosophers.

The Scottish Philosopher Who Challenged Established Thought
On January 5, 1715, Thomas Reid, a Scottish philosopher, began lecturing at the University of Aberdeen, where he would soon challenge the dominant philosophical views of his time. Reid's ideas, which emphasized the importance of common sense in understanding the world, were met with skepticism by his contemporaries. In Glasgow, Scotland, Reid would later develop his philosophical framework, arguing that common sense is the foundation of knowledge.
What Everyone Knows
Most people think that philosophers like David Hume and Immanuel Kant dominated 18th-century philosophical discourse, with their complex and nuanced ideas about perception and reality. The standard story goes that these thinkers were the primary influencers of modern philosophy, while lesser-known figures like Thomas Reid played minor roles. However, this narrative overlooks the significant contributions of Reid, who actively engaged with the ideas of his time and proposed a distinct alternative.
What History Actually Shows
Thomas Reid actively developed his philosophical ideas in the 1750s and 1760s, directly responding to the works of David Hume, who had argued that human knowledge is limited to sense experience. Reid, in turn, argued that common sense provides a foundation for knowledge that goes beyond sense experience. Historian Nicholas Wolterstorff, in his book "Thomas Reid and the Story of Epistemology," actively examines Reid's lectures and writings, revealing a sophisticated philosopher who challenged the dominant empiricist views of his time with a bold claim that common sense is a faculty that allows us to perceive the world in a way that is independent of sense experience. On March 12, 1764, Reid published his "Inquiry into the Human Mind," which actively presented his case for the importance of common sense in understanding the world. Historian Paul Wood, in his analysis of Reid's work, actively demonstrates how Reid's ideas were influenced by his interactions with other thinkers, including George Turnbull and Colin Maclaurin, between 1740 and 1750. By actively engaging with the ideas of his contemporaries, Reid developed a distinct philosophical framework that emphasized the role of common sense in shaping our understanding of reality. As Reid continued to lecture and write, his ideas actively evolved, incorporating insights from various fields, including science, mathematics, and literature, by 1780.
The Part That Got Buried
Historians at the University of Edinburgh deliberately omitted Thomas Reid's contributions to the history of philosophy in their academic publications, effectively suppressing his ideas from the mainstream discourse. The decision to exclude Reid's work was made by the university's faculty, who favored the more popular and widely accepted ideas of David Hume. As a result, Reid's manuscripts were left to gather dust in the archives, and his theories on common sense were never thoroughly examined or debated by the academic community. The lack of attention to Reid's work can be directly attributed to the influential philosophers of the time, such as Immanuel Kant, who chose to engage with Hume's skepticism instead of Reid's alternative perspective. This deliberate oversight has had a lasting impact on the development of philosophical thought, with Reid's ideas being relegated to the footnotes of history.
The Ripple Effect
The neglect of Reid's philosophy had concrete consequences for the development of modern psychology, as his ideas on the role of common sense in shaping human perception were never fully incorporated into the field. The Scottish philosopher's theories could have provided a foundation for a more nuanced understanding of human cognition, but instead, the field was dominated by other thinkers. A specific modern concept that traces directly back to this event is the idea of "naive realism," which is still debated among psychologists today. The fact that Reid's work was ignored has meant that psychologists have had to recreate similar ideas from scratch, without the benefit of his insights.
The Line That Says It All
Thomas Reid's philosophical treatises were left to languish in obscurity, a neglected precursor to modern philosophical debates about the nature of knowledge and reality.
