Is consciousness Causality?

I just started reading Bernardo Kastrup’s work and I’m stuck on a very basic issue.<br><br>Consciousness is causally impotent; it doesn’t effect the external physical world. However, that doesn’t mean that it’s not causally potent. Free will is a perfect example of internal causality. For example, the thought “I’m hungry” can cause me to make the decision to eat something.<br><br>Kastrup implies that consciousness is still causal potent when he says that the external world can cause internal experiences. For example, looking at a red rose can cause me to experience the sensation of redness. <br><br>If the external physical world can cause the internal sensation of redness, then isn’t the external physical world causal potent? If so, isn’t consciousness still the effect? <br><br>I don’t want to strawman Kastrup, so I wanted to see if you all had any thoughts on this.
