The comedian Lily Tomlin said that reality is a crutch for people who can 't handle drugs. Some
philosophers also have a. Low opinion of reality seeing it, as a mere construction of people 's minds or
social contexts. In contrast this chapter,, Argues that the things investigated by science exist
independently of our minds construed as, brains. Using perception and. Inference brains can, develop
.Objective knowledge of reality including knowledge, relevant to assessing the meaning of life.
The previous chapter s conclusion. ' That minds are brains has major implications for two central
philosophical questions: what is reality and how, do we know. It? These questions, are interrelated as
consideration of what things exist needs to fit with discussion of what it takes. To gain knowledge
.About those things. For example an empiricist, who believes that knowledge can come only through
the senses might conclude. That physical objects such as lions and mountains are, not real because we
sense only features, of them not the things themselves.? At the, other extreme an idealist who believes
.That reality is inherently mental might also conclude that lions and mountains cannot be said to be real
apart from how. We think about them.
I think that lions and mountains are real and so, are clouds and electrons. But the hypothesis that
minds. Are brains does not support a kind of naive realism according to which things are just as we
perceive or conceive them to. Be.We know enough about how brains work to show that both
perceiving and theorizing are highly constructive processes involving. Complex inferences.
Nevertheless there are, good reasons to, believe that when the brain is, working well it achieves
knowledge. About the reality of both everyday objects like mountains and theoretical scientific entities
like electrons.This chapter shows how brain science and philosophical reflection together support a
kind of, constructive realism the. View that reality exists independently, of minds but that our
knowledge of it is constructed by brain processes.
I aim to. Show that constructive realism is superior to alternative theories of knowledge and reality
offered by different variants. Of skepticism empiricism,,And idealism. Skepticism is the view that we
have no knowledge at all so that, any talk of the nature of reality is, pointless. Some ancient Greek
philosophers advocated an extreme form of skepticism according to which neither sensation nor
opinion. Could give us any grounds for separating truth from falsehood. An influential current form of
.Skepticism is found in Postmodernist philosophers and literary theorists who view the world as a text
open to many kinds. Of interpretations none of, them demonstrably better than the others. In fields such
as history anthropology and cultural,,, Studies it has, become fashionable to claim that reality is just a
social construction so that, the idea of objective knowledge. Is only a myth.I will try to show how
objectivity is possible through the complex perceptual and theoretical abilities of our, brains. Brains
are not mirrors, of nature but they are powerful instruments for representing it.
Empiricism tries to avoid skeptical. Problems by restricting knowledge to what can be perceived
by the senses.From early modern philosophers such as John Locke and David Hume to later thinkers
such as Rudolf Carnap and Bas, van Fraassen. The restriction of knowledge to sense experience has
had strong appeal. I will show however that strict empiricism is,,, Incompatible both with the
neuropsychology of perception and with the practice of science. Our brain processes are fortunately,,
