People resist new knowledge for fear of the changes it brings. In this sense, what keeps humans in the cave is the fear of changes and the stability that the cave proposes.
We can arrive at this answer because:
- The allegory of the cave written by Plato shows how humans are likely to want to remain in the stability that appearances and lack of knowledge provide.
- In this case, humans avoid new knowledge, as it would completely transform and modify the life they are used to.
In summary, people are afraid of everything new and for this reason, they often prefer to avoid what is new and can modify what they already know, for fear of the consequences.
