Rationabilitas, Rationalitas, et Probabilitas: Understanding the Burden of Proof in Belief Discourse

Published on 16 July 2023 at 08:52

Let's delve into the topic of beliefs. Not our own beliefs, but beliefs themselves, particularly in relation to "lack of belief" atheists. This discussion aims to explore how these atheists perceive beliefs, without any intention of attacking them. This entry seeks to address the intriguing dynamics that exist between certain atheists and beliefs.


Let's begin by examining the concept of belief and what it entails. Believing something essentially means accepting that it is true or likely to be true. It involves embracing a specific proposition or standpoint as true or probably true. Alternatively, we can view belief as the acceptance of a particular proposition. For instance, if I inform you that my name is Anthony and you accept that statement as true, then you believe my name is Anthony. Conversely, if I state my name as Anthony, but you believe it to be Chad, then you do not believe my name is Anthony.


In all honesty, each one of us possesses beliefs ranging from the trivial and inconsequential to the profound and worldview-defining. To address the contentious nature of this topic, I would like to clarify something. I firmly believe in evolution, which means I accept the theory of evolution through natural selection as a valid and true proposition. Furthermore, we can delve deeper into this concept. I argue that belief can be both objectively true and justified, which elevates it from a mere belief to knowledge. Indeed, the distinction between belief and knowledge is not directly relevant to our current discussion. However, it is worth noting that knowledge is, in fact, a subset of belief. To have knowledge of something, one must first hold a belief in that particular thing. However, it is possible to hold beliefs without necessarily having knowledge of the particular thing.


There exists a substantial body of robust philosophical discourse centered around the justification of beliefs and the factors that render them warranted. However, for the purpose of this discussion, we shall set aside those aspects as they are not directly relevant. What holds relevance, in my opinion, is the peculiar and arduous relationship some individuals have with their beliefs. I firmly believe that this stems from a misunderstanding of the requirements for epistemic justification in holding a belief, which stands in direct contradiction to the actual state of affairs. In fact, attaining knowledge necessitates a considerably stronger epistemic justification compared to merely holding a belief. Nevertheless, it is important to note that belief itself is not inherently detrimental; on the contrary, it plays a vital role in the acquisition of knowledge.


Beliefs can indeed be formed for a wide range of reasons, whether they stem from trivial or substantial sources, such as a thorough and meaningful study of a subject. However, it is essential to recognize that the diversity of reasons behind one's beliefs does not undermine the fundamental nature of belief itself. Ultimately, belief is a subjective experience that hinges on what an individual finds personally convincing. Moreover, it is worth noting that the level of education and knowledge an individual possesses often influences the degree of persuasion required to convince them or lead them to accept a proposition as true. In other words, the more informed and educated someone is, the higher the standard of evidence or justification needed to sway their beliefs. Therefore, while beliefs can arise from various grounds and perspectives, understanding an individual's personal convictions and the factors that shape them can shed light on the complexity of belief formation and the role of education in influencing the threshold for accepting new ideas.


With that being said, let's address the core issue at hand. Beliefs have garnered a negative reputation among atheists due to the prevalence of poorly reasoned religious beliefs. Frequently, these beliefs are held by individuals who have never engaged in critical thinking and lack the ability to construct a coherent argument. Moreover, many atheists find themselves repelled by certain Christians, such as young earth creationists, who incessantly impose their views by aggressively asserting, "You believe in evolution." This is precisely why I emphasized this particular point at the beginning of my discussion.


This brings us to what I believe is the crux of the matter: the burden of proof, also known as onus probandi. In essence, when someone makes a claim during a discussion or debate, it is their responsibility to provide sufficient evidence and demonstrate the validity of that claim. The primary source of confusion often arises from the interpretation of meeting the burden of proof. Indeed, the term "burden of proof" can be misleading and prone to misunderstanding, particularly due to its association with legal systems worldwide. The commonly perceived meaning of the burden of proof in legal contexts differs from its application in other discussions or debates. This discrepancy can contribute to confusion and misinterpretation of its actual concept.


When examining the concept of the burden of proof, particularly in criminal law, both the European Union and the United States adhere to the principle of proving guilt "beyond a reasonable doubt." This stringent standard is deliberately implemented to safeguard the rights and innocence of individuals involved in legal proceedings. As the saying goes, "It is better that ten guilty persons escape than that one innocent suffer" (Blackstone's formulation). This enduring principle highlights the fundamental belief that the risk of wrongful conviction must be minimized even if it means allowing some guilty individuals to evade punishment.


If one were to apply the "beyond a reasonable doubt" standard of burden of proof to all everyday situations, it could indeed pose challenges in comprehending the world around us. The high threshold required in legal contexts may not be practical or feasible in every aspect of life. Everyday situations often require us to make judgments, form opinions, and make decisions based on incomplete information or varying degrees of certainty. In such cases, it may be more reasonable to adopt a balance of probabilities or a preponderance of evidence approach, where we evaluate the available evidence and make judgments based on what is more likely or probable. This allows for a more pragmatic and nuanced understanding of the world, acknowledging that certainty levels can differ across different domains and circumstances.


While the burden of proof in legal settings is stringent for the sake of justice, everyday life necessitates a more flexible approach to navigate and make sense of the complexities we encounter. This is exactly how Philosophy views the burden of proof.  While demonstrating something beyond refutation is a lofty ideal, it is important to acknowledge the inherent challenges in achieving absolute certainty, especially in philosophical discussions. Philosophy often deals with abstract concepts, subjective perspectives, and diverse interpretations, making it difficult to reach universally indisputable conclusions.


In philosophical discourse, the emphasis is often on presenting well-reasoned arguments, supporting them with evidence and logical consistency. The aim is to provide compelling justifications for one's claims and engage in rigorous intellectual exploration. However, even the most robust arguments in philosophy can be subject to counterarguments, alternative perspectives, or ongoing debate among scholars. It is crucial to approach philosophy with an open mind, recognizing that it is a dynamic and evolving discipline that encourages critical thinking and the exploration of different viewpoints. Rather than seeking absolute certainty, the value lies in the process of inquiry, fostering intellectual growth, and gaining a deeper understanding of complex philosophical questions.


 In the realm of philosophy, meeting the burden of proof involves providing support for one's position and demonstrating its rationality and reasonableness. Philosophical discussions often revolve around exploring ideas, examining arguments, and evaluating their coherence and logical soundness. While it may be unreasonable to expect an absolute, irrefutable proof in philosophy, it is crucial to present well-founded reasoning, evidence, and logical consistency to support one's beliefs or philosophical concepts. This approach allows for the critical examination and constructive dialogue necessary for intellectual progress. Holding philosophical beliefs to a higher standard of proof, akin to the legal standard of "beyond a reasonable doubt," would indeed be impractical and untenable. Given the abstract nature of philosophical concepts and the diversity of perspectives, it is more fruitful to engage in thoughtful discourse, assess the strengths and weaknesses of various arguments, and strive for rationality and reasonableness in our philosophical positions.


The crux of the burden of proof lies in two essential stages: demonstrating reasonability and rationality, followed by establishing a higher probability. Once a position or belief is shown to be reasonable and rational, the onus then shifts to demonstrating its likelihood or probability. These two stages encapsulate the core essence of the burden of proof. It is important to recognize that individuals have the right to reject a position even if they feel the reasonability and rationality have not been adequately demonstrated to them. Such rejection does not imply a failure to meet the burden of proof. The persuasiveness of an argument is subjective and dependent on the individual's perspective, and it is perfectly acceptable for people to have differing standards of conviction. This message is particularly relevant to fellow atheists, urging them to grasp the nuances of the burden of proof. Understanding that meeting the burden involves showing reasonability, rationality, and probability can foster constructive dialogue and mutual respect, even in matters of belief. By acknowledging the stages of the burden of proof and appreciating the individuality of what is convincing, we can engage in meaningful discussions while respecting the diverse perspectives and levels of conviction among individuals.


In conclusion, the confusion between the burden of proof in philosophy and its application in the legal system has created an unusual dynamic when it comes to beliefs. It is important to recognize that beliefs are inherent to philosophical inquiry, and claiming to have no beliefs would imply a philosophical emptiness.


Attempting to apply the legal standard of the burden of proof to everyday life or philosophy would be unreasonable and impractical. Everyday situations and philosophical discussions often require a more nuanced approach, taking into account varying degrees of certainty and considering a balance of probabilities. It is crucial to avoid the simplistic notion that beliefs must be proven beyond a reasonable doubt in all contexts. Embracing the complexities of belief formation and the exploration of philosophical concepts allows for a more open-minded and intellectually stimulating discourse. By recognizing the distinct nature of the burden of proof in philosophy and appreciating the value of beliefs in philosophical inquiry, we can navigate the realm of beliefs and engage in meaningful philosophical discussions without falling into the trap of oversimplification.
