Evolutionary and Biological Constraints
The mainstream scientific view, rooted in evolutionary biology and cognitive science, posits that human cognitive faculties are biological adaptations shaped by natural selection for survival on Earth. This perspective suggests that our brains are not universal computers but are specialized for specific ecological niches. Just as a feline's brain is not wired to understand macroeconomic theory, the human brain likely possesses inherent "cognitive closure" toward certain aspects of reality. According to thinkers like Noam Chomsky and Steven Pinker, our mental apparatus is constrained by innate structures. As explored in discussions on (https://medium.com/@philosophy.101/can-science-explain-everything-the-limits-of-empiricism-and-rationalism-8b38a31ab821), our sensory and neurological architecture evolved to navigate a three-dimensional world at medium scales of time and space. Consequently, phenomena that exist at the extreme scales of the quantum or the cosmic may remain permanently unintuitive or even theoretically inaccessible because they fall outside the conceptual categories provided by our evolutionary biology.
Epistemological Limits and Mysterianism
A second major argument involves the philosophical concept of "misterianism," particularly regarding the mind-body problem. Philosophers like Colin McGinn argue that certain fundamental questions about the universe—such as how physical matter gives rise to subjective experience—may be cognitively closed to humans. This is not due to a temporary lack of data, but because the human mind lacks the specific conceptual hooks or logical bridge necessary to connect physical states with qualitative feelings. The mainstream view in philosophy of mind often acknowledges that human reason, while powerful, is a finite tool. The inquiry into these (https://philosophynow.org/issues/159/What_Are_The_Limits_of_Knowledge) limits highlights that just as our physical strength is limited, our intellectual capacity to model complex, multi-dimensional, or non-linear systems may hit a ceiling where the complexity of the object exceeds the processing power of the observer.
Logical and Mathematical Irreducibility
From a mathematical perspective, some mainstream theorists argue that the universe may contain truths that are unprovable or uncomputable. If the laws governing the universe are of a complexity that cannot be compressed into human-understandable algorithms, then those laws will remain forever opaque. This view suggests that while we can use mathematics to model behaviors, the fundamental essence of those behaviors may remain outside the human grasp. The distinction between "problems" (solvable within human frameworks) and "mysteries" (unsolvable due to framework limitations) is a cornerstone of this outlook, asserting that our cognitive horizon is finite and constrained by the limits of symbolic logic and processing.
Conclusion
The prevailing mainstream consensus in cognitive science and philosophy is that human understanding is inherently limited by our biological, neurological, and linguistic architecture. While human knowledge continues to expand through social cooperation and technological tools, we remain finite beings within an overwhelmingly complex system. Thus, there are mysteries that will likely remain beyond the reach of human cognition, regardless of future scientific or technological advancements.

Cognitive Closure and Biological Finitude
The perspective of Cognitive Closure suggests that the human mind is a biological organ with specific, finite evolutionary functions, which naturally entails structural limitations. Just as a canine lacks the neurological architecture to comprehend the nuances of quantum chromodynamics, humans may be cognitively closed to fundamental aspects of reality, such as the hard problem of consciousness or the origin of the universe. This view argues that our inability to solve certain philosophical mysteries is not due to a lack of data, but because our brains are simply not built to process those specific types of truths. It steelmans the idea that understanding is a biological capability rather than a universal right, placing humans within the animal kingdom as beings with a high but ultimately walled-off intellectual ceiling.

Model-Dependent Realism and Ontological Opacity
This view posits that we can never understand reality as it is in itself, only the models our brains and instruments construct. There is no theory-independent concept of reality; instead, we operate within a framework where multiple, even conflicting, models can be considered equally valid if they predict observations correctly. As discussed in (https://philosophynow.org/issues/159/What_Are_The_Limits_of_Knowledge), the limits of knowledge are defined by the intersection of our sensory apparatus and our logical frameworks. Consequently, the notion of understanding anything in principle is a category error; we only understand the internal consistency of our own mathematical and conceptual simulations of the world, never the thing-in-itself.

Radical Perspectivism and the Will to Power
Radical Perspectivism argues that the search for universal understanding is a vestige of theological thinking. This view asserts that there are no objective facts, only interpretations driven by specific biological and psychological needs. To understand something is not to mirror reality, but to simplify and colonize the chaotic becoming of the universe into static, usable concepts. In this framework, the limits of understanding are functional; we understand only what we must to exercise power and survive. Any claim to grasp the absolute is merely an expression of the will to power—a psychological drive to impose order on a fundamentally irrational and perspectival existence rather than a discovery of objective truth.

Transhumanist Epistemic Expansion
Transhumanist Epistemic Expansion suggests that current human limits are merely a temporary biological bottleneck rather than a permanent metaphysical boundary. This perspective argues that while unaugmented humans are trapped by the constraints of neurobiology, the integration of brain-computer interfaces and artificial general intelligence will allow for higher-dimensional comprehension. This shift addresses the debate over whether science can explain everything, as seen in (https://medium.com/@philosophy.101/can-science-explain-everything-the-limits-of-empiricism-and-rationalism-8b38a31ab821), by proposing that the knower is an evolving entity. By offloading cognition to synthetic substrates, we may eventually grasp concepts that are currently unthinkable, effectively turning in principle limits into solvable engineering hurdles.
