It is said that 'things are things because of mind'. Thoughts are (relative) things as much as rocks are (relative) things. No consciousness = no things as I understand it. If nothing in this reality really exists without consciousnes as a co-cause that would include both thoughts as well as rocks. Cause and effect. No beginning, no end. Even quantum physics seems to agree that consciousness affects the reality of things (Uncertainty Principle) Anyway, that is how I see it to be.
