The installation is a metaphor for conveying the thought that truth and knowledge can never be permanent. The entire process of learning, unlearning and learning something new continues. The bench represents a transient space - as it is in its physical self. This physical nature of the bench is compared to the interim nature of knowledge.
The bench is not complete in its finishing so as to show to the humility of never being able to know everything. However, I'd like to refine this so as to make it look deliberate - something that it lacks at this stage.
The damaged end of the plank is intentionally done to show that the future can hold what we did not expect. To counter this the solid plank shows that the future might just hold what we've now predicted. This brings about a balance and a sense of relief that some things might still be in our control.
