IB Theory of Knowledge

Knowledge Issue: Truth and certainty cannot always be found in the senses.

Skill Set: Linking the areas of knowledge.

In theory of knowledge, students learn the areas of knowledge through the ways of knowing

which consist of emotion, logic, linguistics as well as sense perception. Sense perception is a way in

which students gain their knowledge through their senses. For instance, some people are visual learners

while others are auditory learners. Visual learners learn from using their sense of sight such as looking at

pictures, diagrams and charts. On the other hand, auditory learners learn by their sense of hearing, they

learn by listening to a lecture or a presentation. Either way, with the five senses, people can explore the

makes you think, you have found water. Therefore, this indicates that your brain can sometimes lie to

you which in turns makes your senses unreliable.

An empiricist is considered to be someone who believes that people obtain their knowledge

my knowledge and experience. For example, if someone tells me that mint chocolate chip ice-cream is

good, I will not believe them until I taste the ice-cream myself. This trust in our senses comes from our

trust in ourselves. Like the example mentioned above, you have to try things for yourself, if someone

else tries something, you do not believe them as much as you believe...
