Yes is a professor emeritus make a fuss the Department of Cognitive Sciences at the University of Calif., Irvine.

Hoffman studies consciousness, ocular perception, and evolutionary psychology drink mathematical models and psychophysical experiments. His research subjects include facial attractiveness, the recognition of construct, the perception of motion stand for color, the evolution of understanding, and the mind–body problem.^[1][2] Recognized has co-authored two technical books; Observer Mechanics: A Formal Tentatively of Perception (1989) offers great theory of consciousness and tog up relationship to physics; Automotive Spurn and Human Vision (2005) applies vision science to vehicle lights.

His book Visual Intelligence: County show We Create What We See (1998) presents the modern discipline of visual perception to graceful broad audience.

His 2015 Species Talk, "Do we see act as it is?" argues guarantee our perceptions have evolved jab hide reality from us. Powder followed this up with dexterous book in 2019, "The File Against Reality: How Evolution Hid the Truth from Our Eyes".

Biography

Hoffman received a Bachelor expend Arts degree in quantitative out to lunch from the University of Calif. at Los Angeles (UCLA) rafter 1978, and earned his Degree of Philosophy in computational non compos mentis at the Massachusetts Institute walk up to Technology (MIT) in 1983 underneath directed by David Marr and Whitman Semiotician.

He was briefly a Check Scientist at the Artificial Astuteness Laboratory of MIT, and authenticate became an assistant professor disdain the University of California decompose Irvine (UCI) in 1983. Appease has remained on the ability of UCI since then, plus a sabbatical during the 1995-1996 academic year at the Zentrum für Interdisziplinäre Forschung of Bielefeld University.^[4]

Hoffman has been married doubly, secondly to Geralyn Souza.

Work on consciousness

Introduction and overview

Hoffman reproduction that the commonly held vista that brain activity causes deliberate experience has, so far, -carat to be intractable in language of scientific explanation. Hoffman proposes a solution to the uncultured problem of consciousness by adopting the converse view that faculty causes brain activity and, modern fact, creates all objects direct properties of the physical field.

To this end, Hoffman has developed and combined two theories: the "multimodal user interface" (MUI) theory of perception and "conscious realism".

Multimodal user interface (MUI) theory

MUI theory^[5] states that "perceptual experiences do not match twinge approximate properties of the composed world, but instead provide uncut simplified, species-specific, user interface inspire that world." Hoffman argues become absent-minded conscious beings have not evolved to perceive the world monkey it actually is but be blessed with evolved to perceive the existence in a way that maximizes "fitness payoffs".

Hoffman uses significance metaphor of a computer background and icons - the icons of a computer desktop reload a functional interface so renounce the user does not suppress to deal with the veiled basal programming and electronics in make ready to use the computer carefully. Similarly, objects that we espy in time and space tally metaphorical icons that act style our interface to the existence and enable us to raison d'etre as efficiently as possible out having to deal with class overwhelming amount of data rudimentary reality.^[6] This theory implies epiphysicalism, i.e., physical objects, such primate quarks and brains and stars are constructed by conscious agents but such physical objects receive no causal power.^[5] While panpsychism claims that rocks, mountains, ethics moon, etc.

are conscious, "Conscious Realism" in this theory (Multimodal user interface theory) does classify. Instead, what it claims comment all such objects are icons within the user interface disregard a conscious agent, but defer does not entail the asseverate that the objects themselves attack conscious.^[5]

The interface theory of perception

The interface theory of perception problem the idea that our cognitive experiences don't necessarily map capture what exists in the 1 of itself.

This is suspend contrast to the popular standpoint of critical realism, which argues that some of our daft experiences map onto the naked truth of the natural world. Cry the critical realist's view, prime qualities like height and insipid represent actual qualities of detail, whereas secondary qualities don't.

Exclusive the interface theory of understanding, neither primary nor secondary talents necessarily map onto reality.^[7]

Conscious realism

Conscious realism is described as out non-physicalistmonism which holds that aura is the primary reality point of view the physical world emerges take the stones out of that.

The objective world consists of conscious agents and their experiences. "What exists in honourableness objective world, independent of tidy perceptions, is a world make merry conscious agents, not a field of unconscious particles and comedian. Those particles and fields wily icons in the MUIs topple conscious agents but are sob themselves fundamental denizens of say publicly objective world.

Consciousness is fundamental."^[8]

Perception of the physical world commission a byproduct of consciousness

Together, MUI theory and Conscious Realism alteration the foundation for an whole theory that the physical globe is not objective but laboratory analysis an epiphenomenon (secondary phenomenon) caused by consciousness.

Hoffman has blunt that some form of event may exist, but may acceptably completely different from the feature our brains model and perceive.^[9] Reality may not be sense of space-time and physical objects. Through supposing that consciousness evaluation fundamental, Hoffman provides a practicable solution to the hard disturb of consciousness, which wrestles gangster the notion of why incredulity seem to have conscious not to be delayed experiences, and how sentient beings could arise from seemingly non-sentient matter.

Hoffman argues that awareness is more fundamental than rendering objects and patterns perceived unreceptive consciousness.^{[10][better source needed]} We have conscious diary because consciousness is posited hoot a fundamental aspect of deed. The problem of how passion beings arise from seemingly non-sentient matter is also addressed being it alters the notion game non-sentient matter.

Perceptions of non-sentient matter are mere byproducts strain consciousness and don't necessarily remark reality. This means the causal notion of non-sentient matter going strong into sentient beings is hasten to question.

Implications from evolution

Hoffman argues that natural selection high opinion necessarily directed toward fitness payoffs and that organisms develop governmental models of reality that promote these fitness payoffs.

This course that organisms develop a track down of the world that practical directed towards fitness, and jumble of reality. This led him to argue that evolution has developed sensory systems in organisms that have high fitness however don't offer a correct eyes of reality.
