Light as a condition of sight was the conclusion, hence the reason why light and its workings were mentioned only once.
It's not a conclusion, as it does not follow from the other things he says.
NoIf you didn't follow me this whole time, then you will keep insisting that he was wrong because he didn't explain how light works.
I followed. He makes no such explanation, hence my question.
Light does what light does, bilby. It travels at 186,000 miles a second. In the absence of light, we cannot see that thing. He never said we could.
Then it is undeniable that we cannot see that thing until the light has travelled to us; And that therefore his claim that we see in real time is false, because such a claim contradicts "In the absence of light, we cannot see that thing".
No bilby, there is no absence of light in this version
Yes, there is. I literally just quoted you saying that there is. "In the absence of light, we cannot see that thing".
There is no absence of light in this version. If there were an absence of light, we could not see that thing, but there isn't a gap. It is the light that allows us to see said object, but in order to see said object --- in real time --- it must meet the requirements for sight, which are luminosity (there has to be light at the eye), and the object's size (too small or too distant, there will be no light in which to see said object.)
There can be no "because" when you contradict yourself.
I am not contradicting myself, though. Light travels at a finite speed. Photons continue to be replaced, but the image (the object's wavelength and frequency) does not travel away from the object over space/time. That's why he wrote the following:
“Well, I say, what difference does it make whether we have four senses and a pair of eyes instead of five senses? I certainly don’t feel any different, and I still see you just as before.”
“Once it is understood that something existing in the external world makes contact with the brain through the four senses, but that the brain contacts the various objects by peering through the eyes, it makes a huge difference, and many things can be clarified.
Our scientists, becoming enthralled over the discovery that light travels approximately 186,000 miles a second and taking for granted that five senses were equally scientific, made the statement (which my friend referred to and still exists in our encyclopedias) that if we could sit on the star Rigel with a very powerful telescope focused on the earth, we would just be able to see the ships of Columbus reaching America for the very first time. A former science teacher who taught this to her students as if it were an absolute fact responded, “I am sure Columbus would just be arriving; are you trying to tell me that this is not a scientific fact?”
Again, my reply was, “Are you positive because you were told this, or positive because you, yourself, saw the relations revealing this truth? And if you are still positive, will you put your right hand on the chopping block to show me how positive you really are?”
“I am not that positive, but this is what I was taught.”
Once again, certain facts have been confused, and all the reasoning except for light traveling at a high rate of speed is completely fallacious. Scientists made the assumption that since the eyes are a sense organ, it followed that light must reflect an electric image of everything it touches, which then travels through space and is received by the brain through the eyes. What they tried to make us believe is that if it takes 8 minutes for the light from the sun to reach us, it would take hundreds of years for the reflection of Columbus to reach Rigel, even with a powerful telescope. But why would they need a telescope?
there is no time element.
Doesn't matter. "In the absence of light, we cannot see that thing". No mention of time here.
To repeat: If there is no light, because the celestial object is too far away or too small to be seen with the naked eye or with a telescope, there will be no light and no luminosity, which is a requirement.
You are thinking that light has to travel to us, or there would be no light in which to see the object.
I am only thinking that because YOU say so:
"Light does what light does, bilby. It travels at 186,000 miles a second. In the absence of light, we cannot see that thing. He never said we could."
But you're just restating the afferent version of sight, which is the very version he challenged.
No, I am repeating your very own words.
You are contradicting yourself. I am just pointing it out. If you don't like the fact that your position is contradictory, take it up with
@peacegirl, she's the one who is making claims that contradict each other.
My words are not contradictory. Photons travel in packets of electromagnetic energy, but these packets of energy do not bounce off objects and travel with an object's wavelength and frequency through eons. It's similar to a mirror image. A mirror image doesn't travel beyond the object's reflection, except in this case, the reflection is at the eye instantly as we focus on the object itself, which means we are not receiving the image from light through space/time, which is the present-day belief. That is what he meant when he said light is a condition of sight, not a cause.
