Yes. Though i think you're committing the gentic fallacy here, which is the core fallacy at the heart of idealism and much 19th C. german philosophy.
The properties of the origin of somethign imply nothing about the properties of the product. That a bread factory is made of metal, does not mean bread is.
That in my statement of things in language I am conscious of what I state, says nothing about the truth (or other such properties) of what I say.
A photographic plate is made of metal, the mountain it photographs, of mud.
I am conscious, but when I say, "reality is all that which is extended in space and time" -- the truth of that proposition has nothing to do with my being consiouss -- it is a loaf of bread, a photograph, a product of a process invovling consiousness but in none of its properties, depends upon it.
Every relevant thing we do requires consciousness -- just as everythign a thermometer does requires, say, its own mercury -- but in measuring coffee's temperature, coffee is in no way mercury. And when we measre the world, by photographing it with consciousness, it is in no way conscious.
You are attributing to me something I never said.
I said nothing about the nature of reality. All that I said is: all my knowledge of the reality (whether it exists independently or me or not) comes from my perception.
There could be an objective reality, or reality could be something created by our consciousness. I don't know. The one thing I do know, however, is what my consciousness perceives. It is in that sense that is is fundamental
>reality is all that which is extended in space and time
You are missing the fact that "space" and "time" are also illusions painted on consciousness.
