what is an inductive type of argument?
Reasoning from the specific to the general.
what is a deductive type of argument?
Where arguments can be explained as reasoning from the general to the specific (i.e. they can be deduced).
what is meant by argument from authority?
A common, weak form of argument. It is reasoning based on the similarities between two or more things.
what is meant by a causal argument?
A weak type of argument that claims that one thing happened as a direct results of something occurring.
what is meant by argument from analogy?
Often described as a ‘fallacy’, this type of argument is often offered by an experts and is based on their views.
what is the difference between fact and opinion?
fact: A fact is objective and can be confirmed and supported by evidence. A fact’s accuracy can be established.
opinion: is subjective and concerns an individual’s feelings
give an example of a deductive argument
PREMISE (previous statement):There are always 3 angles in a triangle.
The total number of degrees in the angles of the triangle is always 180.
Two of the angles in this triangle add up to 150 degrees.
CONCLUSION (deductive argument):Therefore, the third angle must be 30 degrees.
give an example of an inductive argument
Premise: For the past 50 years it has always rained in the first week of April in the Lake District.
Conclusion: Therefore, it will rain in the first week of April next year in the Lake District.
(The conclusion cannot be certain but may be very likely).
give an example of an argument from analogy
Because two things are similar, they will react in similar ways/share similar characteristics.
give an example of a causal argument
Something happened as a direct consequence of something else.
Example: She had a poor diet and, therefore, she had a heart attack.
for each statement decide what type of argument it is:
1) Generally, the brains of primates are similar to the brains of humans.
Human brains produce consciousness.
Conclusion: Therefore the brains of primates produce consciousness
2) Birmingham is a city in the West Midlands.
The West Midlands is a region in England.
Conclusion: Therefore, Birmingham is a city in England.
3) All cats that you have observed purr. Therefore, every cat must purr.
4) Suzy is a doctor. Doctors are smart. Suzy is assumed to be smart.
5) Scientists believe that sugar poses more of a threat than fat, therefore, we must cut out certain sugars.
1) Argument from analogy.
2) Deductive argument
3) Inductive argument
4) Inductive argument
5) Argument from authority
what is meant by society?
a group of people who share a defined territory and a culture q
what is a hypothesis?
-a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
how do scientific theories come to be?
- an observation is made
- possible explanations (hypothesis) are given
- the hypothesis are then assessed
- when on is selected a prediction is made
- scientists the design and carry out tests
- if the test is consistent with the explanation then it may become part of a theory if not the scientist go back to another explanation
what type of argument (process) do you think the forming of scientific explanations use?
-induction
give an example where a scientific prediction has been made due to a situation
- In a Viennese hospital a Dr noticed that women giving birth in on ward were dying but others in another part of the hospital were surviving.
- The Dr looked for difference in the two wards and discovered that the surviving women were treated by trainee midwives whereas those in other ward attended by student doctors.
- he realised that the doctors were touching corpses in their anatomy lessons- something that the midwives did not do.
- He suggested that the doctors should wash their hands after anatomy lessons after he saw one of his doctor friends develop a fatal infection whilst dissecting a corpse.
- He had predicted that there may be a link between touching corpses and touching the pregnant women during labour.
- After introducing this practice, with the doctors the mortality rate reduced to that of the midwives’’ ward.
- Semmelweis then made a prediction from this observation and tested it; this later resulted in the theory that minute organisms could cause disease.
what does it mean when a theory can be only considered scientific if it was open to falsification
-this is where scientist deliberately try to find circumstances where the theory could fail and we test it under those conditions to see what happens
what is Occam’s Razor?
-this is where the explanation with the fewest assumptions (simplest) should be used for theories
what questions can science not answer?
questions that do not relate to the physical world such as;
- Those relating to the meaning of life
- The existence of God
- Whether humans or other animals have souls
- Moral questions, such as why don’t we make everyone donate blood?
what are some of the big questions in science and what research if any is done to answer these questions?
- ) what is the universe made of
- astronomers don’t know what 95% of the universe is made of - ) How did life begin?
- some say that life began in hot pools near volcanoes, others say that it was kick- started by meteorites hitting the sea
- Miller-Urey experiment The two scientists sealed a mixture of water, ammonia, methane and hydrogen in a sterile flask. The mixture was heated to evaporate water to produce water vapour. Electric sparks were passed through the mixture of water vapour and gases, simulating lightning. After a week, contents were analysed. Amino acids, the building blocks for proteins, were found. - ) Why do we dream?
- Animal studies and advances in brain imaging have led us to a more complex understanding that suggests dreaming could play a role in memory, learning and emotions. Rats, for example, have been shown to replay their waking experiences in dreams, apparently helping them to solve complex tasks such as navigating mazes.
what is meant by cosmology?
-the scientific study of origins of the universe and galaxies
what were the commonly held beliefs in the greek and middle eastern developments?
- the earth is the centre of the universe
- the earthly universe has a boundary, and heaven lies beyond it
what is the geocentric theory?
this is theory that said that the sun and other heavenly bodies circled the earth, and so earth was the centre of the universe
how did Copernicus challenged the society and science?
- It was thought that the sun and other heavenly bodies circled the earth (the geocentric theory), and so it was accepted that the earth was the centre of the universe
- in the early 16th Century, Copernicus proposed a heliocentric theory
- this was there sun was notional centre of the universe
