The concept of "ideas" can have different interpretations depending on context, so let's clarify what we mean by "ideas" in this context.
If "ideas" are interpreted as mental constructs or perceptions, then yes, matter exists independently of our ideas about it. In this sense, matter exists objectively in the external world, regardless of whether we are aware of it or have any specific thoughts or concepts about it.
For example, a rock exists as a physical object regardless of whether anyone is thinking about it or not. The laws of physics and the properties of matter continue to operate even in the absence of human awareness or conceptualization.
However, if "ideas" refer to the mental representations and interpretations we form about matter, then the existence of matter can be influenced by our ideas to some extent. Human perception and understanding of matter can shape how we interact with it, study it, and utilize it for various purposes.
In summary, matter has an objective existence independent of human ideas, but our ideas and understanding of matter can influence our relationship and interaction with it.
