No. I am reading exactly what he wrote.Right. He said he couldn’t tell if lower order creatures had consciousness. He didn’t say he didn’t know what it is. In fact he believes it is a permanent condition involving all of the senses. There isn’t one thing that makes us conscious. It is the whole being.Is that what you believe he said?Here's what George Wald, Nobel Laureate in Physiology / Medicine and an atheist to boot, has to say about consciousness:
“In my life as scientist I have come upon two major problems which, though rooted in science, though they would occur in this form only to a scientist, project beyond science, and are I think ultimately insoluble as science. That is hardly to be wondered at, since one involves consciousness and the other, cosmology.
The consciousness problem was hardly avoidable by one who has spent most of his life studying mechanisms of vision. We have learned a lot, we hope to learn much more; but none of it touches or even points, however tentatively, in the direction of what it means to see. Our observations in human eyes and nervous systems and in those of frogs are basically much alike. I know that I see; but does a frog see? It reacts to light; so do cameras, garage doors, any number of photoelectric devices. But does it see? Is it aware that it is reacting? There is nothing I can do as a scientist to answer that question, no way that I can identify either the presence or absence of consciousness. I believe consciousness to be a permanent condition that involves all sensation and perception. Consciousness seems to me to be wholly impervious to science."
George Wald, 1984, “Life and Mind in the Universe”, International Journal of Quantum Chemistry: Quantum Biology Symposium 11, 1984: 1-15.
So he also says he hasn't a clue what consciousness is.
No, that is what he said. Did you actually read it?
"There is nothing I can do as a scientist to answer that question, no way that I can identify either the presence or absence of consciousness."
You are reading what you want to see and ignoring the rest. He has clearly stated that he hasn't got a clue what consciousness is. In fact, he seems to be saying that he believes (which is not the same thing as knowing) that you can't know what it is.
"I believe consciousness to be a permanent condition that involves all sensation and perception."
He knows what consciousness is. He doesn't believe it is anything science can measure because it can't be measured because it is not one thing. It is everything together.
Consciousness is an artifact of intelligence. Free will is an artifact of intelligence. The ability to choose distinguishes from the rest of the living world. It's the thing that sets us apart.
