Causal beliefs can determine how we behave.
We cannot tolerate not knowing the cause of important events like illness and death.
The original and only true function of the brain, from and evolutionary viewpoint, is to control movement and interaction with the environment.
That is why plants have no brains.
Causal beliefs make us human and different
from all other animals.
It evolved in relation to use of tools. It led to
religious beliefs.
All cultures have beliefs about causes, but more
than 90% of events have causes not easily
accessible to an individual.
Supernatural explanations are common:
telepathycommunication with spiritshomeopathyghosts and angels
Causal understanding in children is a
developmental primitive.
From 3 months infants can reason about physical causality ; by 7 months objects remain whole, and require contact to move.
By 18 months they can rake a toy to themselves.
By 3 years they understand that people
have different beliefs.
Many questions about causes.

Crows use sticks as tools
Lack of causal understanding
Chimps are at the edge of causal

Kanzi was taught to make tools
The first human tools may have been
the result of a stone breaking when
used on nuts - but causal thinking was
essential
A million or so years in stasis in tool use,
and then some 100,000 years ago new
tools appeared.
Technology requires a concept of
physical cause, and drove human
evolution.
Language may have come from
gesture and throwing. It helped with
causal beliefs.
Technology drove human evolution.Humans could manipulate theirenvironment.
Dunbar argues that it was social understanding that drove human evolution. But what was the bigadvantage?
Religion provided causal understanding.

Science is the best way to understand the
world, but it is unnatural - it goes against
common sense. Archimedes.
Moon; force and motion; quantum mechanics
Galileo and falling body.
No miracle should be believed unless the
evidence was such that it would be miraculous
not to believe in it. David Hume
There is no evidence that the fertilised human
egg is a human being. Implications for stem
cells and abortion.
Intelligent design is based on faith not science.
There will always be some unansweredquestions.
Science is the best way to understand the world.
If the history science were rerun the results would be the same, but DNA might be googy.
Paranormal beliefs invoke forces and causes both outside ordinary experience and science. They offer believers new powers.

Peter Medawar
Placebo effect determined by beliefs
Three general purpose heuristics - availability,
representativeness, and anchoring.
Why did science persist in the West?
Christianity was involved in argument and rationality. They were concerned about thenature of the physical world
Aquinas held that theology was science from God
Many religions believed in rebirth.
No good evidence for Gods
