“It is impossible for a man to learn what he thinks he already knows.”
In my Theory of Knowledge (TOK) class, we questioned several statements in order to challenge the certainty of each claim. I quickly realized, after thinking outside the box, that many statements I hear everyday are not always as definite as I originally assume them to be.
Now, I must apply the skills I gained from TOK class in order to evaluate the certainty . of different pieces of knowledge from each of my IB subjects (I waited to write this blog post until after the process of changing my geography option to history was completed) :
History- Apartheid was an ideology used in the 20th century that supported the segregation of people based on their race = Fixed
Economics- Humans use a cost-benefit analysis in order to make rational decisions = May Change
English (Language/Literature)- Newspaper articles can contain biased personal opinions that influence our beliefs = May Change
Mathematics- Functions have a one to one or many to one relationship = Fixed
Spanish Ab Intio- Most of the time, the ending of adjectives needs to be altered in order to match the “gender” of the noun it is describing = May Change
Chemistry- The temperature of a substance that is undergoing a change in state of matter will remain constant = Fixed
In conclusion, I would rank my IB subject knowledge claims in the following order of certainty (#1 being the most certain) :
- Chemistry = This is a scientific fact, which means that it can be proven to be true.
- Mathematics = This is the set definition of a function.
- History = This can be proven based on historical events and records.
- Economics = Humans are not always rational people.
- English = Some newspapers may actually be unbiased.
- Spanish Ab Intio = Some adjectives do not need to be changed.
Have a great day,
