Different types of knowledge

What are the differences between declarative and procedural knowledge? Declarative knowledge is the knowledge of facts, procedural knowledge is the knowledge on “how to” do something. For example: I know that 5+5=10 (declarative) and I know how to calculate (procedural).

Knowledge, according to Plato, is justified true belief. But this definition does not cover all types of knowledge. You know how to read, for example. This type of knowledge is not based on belief, justification or truth. In this edition we will discuss two different types of knowledge:

What is Knowledge?

Plato defined knowledge as “Justified true belief”. For a person to know something he/she has to believe it, has to be able to justify it and it has to be true. This is explained here.

The tree criteria needed for a person to know something are:

  • Lack of justification: “I know that aliens exist” – there is no way that you can provide a justification for this claim. Therefore you can not know it.
  • Lack of belief: “I know that the world is round but I don’t believe it.” – this is a contradictory statement. For you to know something you have to believe in it. But not every belief is knowledge!
  • Lack of truth: I know that a circle has 3 corners. – You can not know things that are evidently not true.

Four possible ways to justify one’s belief are:

  • Memory
  • Authority
  • Logics
  • Empirical evidence
