This paper investigates the nature of reality by looking at the philosophical debate between realism and idealism and at scientific investigations in quantum physics and at recent studies of animal senses, neurology and cognitive psychology. The concept of perceptual relativity is examined and this involves looking at sense perception in other animals and various examples of perceptual relativity in science. It will be concluded that the universe is observer dependent and that there is no reality independent of the observer, which is knowable to the observer. The paper concludes by an investigation of what an observer dependent universe would be like and that recognition of an observer dependent world would lead to a more open minded and tolerant world.

Sense Perception and Reality examines the remarkable similarities between philosophical idealism and the Copenhagen Interpretation of quantum physics. The book looks at perceptual relativity involving animal senses, neurology and cognitive psychology. It concludes the universe is observer dependent and varies with the sensory apparatus used to observe it. The Copenhagen Interpretation is examined and perceptual relativity would appear to apply in the quantum world. The Copenhagen Interpretation suggests the universe is observer dependent, the same conclusion as is found in philosophical idealism in the macro world. The book concludes by showing such a universe is quite consistent with a modern objective science.
While philosophy of science is the study of problems of knowledge concerning science in general, there also exists - or should exist - a '' philosophy in science'' directed at finding out in what ways our actual scientific knowledge may validly contribute to the basic philosophical quest. Contrary to philosophy of science, which is a subject for philosophers, philosophy in science calls on the services of physicists. When, in its spirit, quantum theory and Bell's theorem are used as touchstones, the two main traditional philosophical approaches, realism and idealism, are found wanting. A more suitable conception seems to be an intermediate one, in which the mere postulated existence of a holistic and hardly knowable Mind-Independent Reality is found to have an explaining power. Some corrections to comments by Schins of a previous work on the same subject are incorporated.
It is often thought that idealism, which affirms that reality is mind-dependent in some relevant sense, leads to antirealism in science. This chapter argues that this common perception gets the cart before the horse. It is rather the case that realism in science, especially in regard to relativistic quantum physics and consciousness, leads to idealism – theistic quantum-informational idealism, to be precise – as the best account of the nature of reality. The chapter outlines the scientific basis for these claims and sketches the arguments for them, starting with an evaluation of the metaphysical significance of relativistic quantum physics for material identity and the character of physical law. It define three basic kinds of realism – metaphysical realism, critical epistemic realism, and critical scientific realism – and evaluate their relationship to theistic quantum-informational idealism as the metaphysical framework unifying the insights into reality that follow from quantum physics and consciousness studies.
In this chapter, I offer some personal reflections about the nature of reality, shaped by my work as a quantum physicist, my experimentation with psychedelic drugs during the 1960s, and my more recent studies of modern cognitive science. Traditionally, questions about the essential nature of reality are asked by philosophers. In the twentieth century, these questions were asked for the first time by scientists as well. During the first three decades of the century, the exploration of the atomic and subatomic world brought physicists in contact with a strange and unexpected reality that shattered the foundations of their worldview and forced them to think in entirely new ways. Quantum physics showed scientists “a new reality,” and from that time on, the nature of reality became a popular subject of discussion not only in philosophy but also in science. In recent decades, cognitive scientists took another radical step in the scientific conception of the nature of reality. They asserted that the features of our ordinary, everyday reality are not features of an independently existing world, but are created in the very process of perception. In a way this generalizes the influence of the act of perception on the perceived object, which was famously analyzed in quantum physics by Werner Heisenberg, to everyday perception. In other words, even our everyday reality is just one of many alternate realities.
In 2005, an essay was published in Nature asserting that the universe is mental and that we must abandon our tendency to conceptualize observations as things. Since then, experiments have confirmed that — as predicted by quantum mechanics — reality is contextual, which contradicts at least intuitive formulations of realism and corroborates the hypothesis of a mental universe. Yet, to give this hypothesis a coherent rendering, one must explain how a mental universe can — at least in principle — accommodate (a) our experience of ourselves as distinct individual minds sharing a world beyond the control of our volition; and (b) the empirical fact that this world is contextual despite being seemingly shared. By combining a modern formulation of the ontology of idealism with the relational interpretation of quantum mechanics, the present paper attempts to provide a viable explanatory framework for both points. In the process of doing so, the paper also addresses key philosophical qualms of the relational interpretation.
Scientific realism holds that the objects of scientific knowledge exist independently of the minds or activities of scientists and those scientific theories are true of that objective world. This is antithetical to the posits of quantum physics, a body of knowledge taken as the seal of the sciences because of its incredible feat, which emphasizes observer created reality, and to that end subjective and probabilistic understanding of realities. Given this background, we contend that, if the thesis of scientific realism were to be taken as sacrosanct, nature would have remained somewhat unfavourable since nobody would have dared to ‘create’ reality other than those originally imposed by nature. And to the quantum physicist, the resort to probabilistic conception of reality is an obvious indication that nature in its dynamism is uncanny and still has billions of tricks for mankind.
