In my opinion, every kind of living entity that survives, must also have this willingness for growth built-in. In my opinion, no. Because it is, I think, possible to talk not only of survival of physical entities, but also possible to talk about survival of ideas . Beliefs, methods, thoughts, philosophical systems, scientific models, etc., are all ideas. Philosophy is the action of trying to create new ideas.
Philosophy makes ideas into dynamic things rather than immutable, static givens.
Since philosophy deals with, acts on, and produces new and changed ideas, no idea can be holy to philosophy. In my opinion, then, philosophy is a survival tool. Philosophy can be called useful, because it has the capability of creating ideas that can be useful for survival. Philosophy is living entities changing their own programming. Now about idealism .
