Scottish philosopher Thomas Reid introduces a compelling idea when he says, "If there are certain principles, as I think there are, which the constitution of our nature leads us to believe, and which we are under a necessity to take for granted in the common concerns of life, without being able to give a reason for them—these are what we call the principles of common sense." This statement is foundational to Reid's philosophy of "Common Sense Realism," which postulates that there are self-evident truths or principles that we instinctively know and rely upon in daily life. This article delves into the intricacies and implications of Reid's concept of the principles of common sense.
Understanding Reid's Principles of Common Sense
Reid's notion of common sense principles refers to innate, self-evident truths that are universally acknowledged but often defy rational explanation. These principles act as the foundational building blocks for human cognition, perception, and interaction. For instance, the belief that the external world exists or that other minds are like our own are examples of common sense principles according to Reid.
The Role of Innate Belief
Reid challenges the empiricist view, which holds that all knowledge comes from sensory experience. He argues that there are beliefs we must hold by necessity, irrespective of empirical evidence. These beliefs are innate to our nature and essential for navigating the complexities of life.
Relevance to Ethics and Morality
Reid's concept extends into ethics and morality. The idea that certain moral truths are universally understood without the need for reasoned arguments aligns with the principles of common sense. This suggests a form of moral realism, where ethical principles exist independently of individual or cultural perspectives.
Practical Implications
Decision Making: Reid's principles act as navigational aids in decision-making processes. They serve as intuitive guides that are pre-installed, so to speak, in the human psyche.
Social Contracts: These principles play a role in forming the implicit social contracts that govern human interactions. For instance, the innate understanding of fairness or justice shapes societal norms and laws.
Psychology: In psychology, understanding these principles can help in identifying cognitive biases and decision-making frameworks.
Challenges and Criticisms
Subjectivity: One of the criticisms is that what is considered "common sense" can often be subjective and vary from one individual or culture to another.
Scientific Inquiry: From a scientific perspective, the reliance on innate principles without empirical justification can be seen as problematic.
Conclusion
Thomas Reid's philosophy of common sense principles offers an intriguing lens through which to explore the foundations of human cognition, ethics, and social interaction. He proposes that there are innate truths or principles that the human mind naturally accepts, without requiring empirical evidence or rational justification. These principles serve as the bedrock for our understanding of the world and govern our actions in everyday life. While the concept is not without its criticisms and challenges, it provides a robust platform for discussing the innate structures of human belief and interaction, pushing the boundaries of philosophical inquiry into the nature of reality and human existence.
