if god hadn't made a devil in the first place we wouldn't need a right time to remove it or to be ready for a perfect world, we'd be living in one... we'd accept it because it would be the world we were born into
think about it why do you you brush your teeth is cause thats what you were taught to do. just like if we were taught to live in a perfect world. but if tyhere wasnt evil we wouldnt need a world it would just be hevan.
Just a little fact: Light is not colourless!! Light has a wavelength and it is this which is referred to as colour e.g. red is about 600 nm and white light is a combination of different wavelengths of light. I put this as simple as I can but it is a scientific fact - that's why tv, pictures etc make sense to people - the different wavelengths of light are fundamental parameters of light not a creation of our minds.
I often find, when reading philosophy that some authors grab an incorrect scientific fact - even as incredibly mistaken as the one in this thread (light has no colour - it actually does!) and continue to write a whole book based on this original assumption. Yeah sure - it's thier opinion but they shouldn't act like their assumption is a fact. I don't wanna go into this in any more detail - light has colour - it's fundamental.

ive come to the belief, now, that this is in a way a form of the matrix. i dont mean that robots are controleing the world, but in other aspects. all things have a way to be justified by the matrix.
It's like if you see a blue car go by, and you say to your friend "Hey, a blue car." His perception of blue may actually be green to you. But even if what he sees is a green car fromyour perspective, he has been taught that that color is blue.
to much spookily convenient things happen.....
and waaaay to much deja-vu here,
maybe I believe you

Neo, I understand what you're saying, but I'd like to offer a different perspective which contradicts yours. Although light particles have wavelengths, such wavelengths do not have the intrinsic property of colour. 'Colour' as we know it is merely a manifestation of our sensory perception. As most science students will know, the perception of colour occurs through a series of reactions which begin when light strikes our retinal cells and culminate in its perception by our brain. The fact that light of different wavelengths have different colours is merely due to our brains' perception of it.
Light as we know it is only a small part of the entire electromagnetic spectrum. Electromagnetic waves have wavelengths between 0.001 nanometers and 100 metres, and spans from radio waves to microwaves to the infrared, and from the visible spectrum to the ultraviolet range to X-rays and Gamma-rays. To us, light such as infra-red and ultra-violet light are invisible, and hence, colourless (by the way, the 'violet' glow of UV light and 'red' glow of IR light seen in pictures or lamps in the laboratory are artificially created - we simply do not have the capacity to interpret those wavelengths; special UV/IR cameras, telescopes and instruments produce artificial images which our brains can interpret). However, some animals do indeed see them. But the fact remains that because our retinal cells and brains work differently from other animals, it is likely that each 'colour' as we see it is probably interpreted differently by different animals ie. the 'red' cloth carried by matadors is probably not interpreted in the same manner by bulls. In addition, we may not have the ability to 'see' radiowaves or microwaves, but if an alien from another planet does, then those waves will also have specific colours to the alien.
Which brings us back to the original quote made by murc13lago : 'When light strikes an object, the object absorbs and reflects off the light waves. Light by the way is colorless. The light waves reflected goes into our eyes and is processed by cones and rod then intrepetted by our brain as being red. Color exist solely in us and not in the object....'
This is not an inaccurate statement if taken in the right context. We will never know if light is colourless or not; what we do know is that ultimately what we see may not represent the actual truth - it is merely our interpretation of it. I suppose it's like seeing an abstract piece of art, where innumerable opinions abound. Ultimately, it is in the eye of the beholder. But how do we know what that piece of art truly represents (short of asking the artist)?
The other relevant analogy is in our sense of sight. When the image of objects enters into our eyes, they are inverted. Hence, in reality, the things that we see are actually upside down. Consequently, if we ever meet an alien with different neural networks in their brains, then meeting face-to-face could be a problem, because our visual orientations may be completely different!

if i take a laser of wavelength 632.8 nm wavelength and shine towards a photo-detector the detector will not see it if there are filters in the way that reject 632.8nm light. I can call 632.8nm a shade of red - true colours are labels for wavelengths but the wavelengths are fundamental. In my photodetector if it set to recieve light in at 632.8nm it's because of the quantum mechanical properties of the silicon that makes the detector. We can use quantum mechanics to predict what allowed electron transitions are possible. Experiment confirms this extraordinarily well. light quanta of 632.8nm wavelength are exactly correct for that transition and so it is detected. electrons are fundamental particles. electrons are not a new fangled theory. because the electrons and their properties and experiments involving them are repeatable by different people it confirms that we all measure those properties to be the same. the same is true of photons. Thus the theory of how light interacts with matter is an experience shared by different ppl. When we look at a light source our eyes receieve the same wavelength (colour) of light only the last stage in which our brain percieves them can be different. But an apple is red. even if there was one colourblind person who was the last and only living person in the universe and he held a red apple, as long as say sunlight illuminated the apple it would still be red he would just see it as green.
Research into physics is performed with a scientific method that cross references the experiences of different scientists to prove what is a universal fact for all of us in case one scientist alone is mistaken. Also in the scientific method a scientist can take certain measures such as repeating an experiment, trying different apparatus, trying different methods of experiment etc to check for internal consistrency. Also science does not involve merely interpreting physical evidence it works both ways there are top down and bottum up methods of research. some begin with experiment, other with theory. when a theory is supported by much pracical evidence and when some new observations can be found by an unexpected feature found through the theory we can be quite confident it is scientific fact or there is an enormously great relative frequency that what the theory predicts will happen. Case in point, when Einstein considered the interaction of light with matter it was to explain emission and absorption which was seen experimentally. Out of these theories came the concept of stimulated emission which led to the creation of laser light - which does not exist in nature and had never been seen before. This is something not one person had seen with their eyes (it is safe to look at laser light under certain conditions as through a Fabry-Perot interferometer but don't do it unless you have been trained!!). Since no one had seen laser light it was free of any strange interpretations of the brain and so free of differing interpretations. Thus by using science to understand the universally experienced phenomenon of light a new state of light was predicted and realised which we all can detect in the same way (my cd will play in your cd player for example). That is the greatest thing about science. Whether this is "the real" or a perfect simulacra, science helps us separate what is experienced by all of us and what is unrepeatable, and experienced by only one person.

think about it why do you you brush your teeth is cause thats what you were taught to do. just like if we were taught to live in a perfect world. but if tyhere wasnt evil we wouldnt need a world it would just be hevan.
we brush our teeth because we need to otherwise they rot and become useless. Think of a better comparison.
If there wasnt evil in the world...how would we know its good.
Plus the world is perfect.......its the people that live on it that arent
Its like the Matrix infact
We are given CHOICE (free will) because God only wants us to choose to have a relationship with him. Think about it isnt it great when some one likes you for being yourself not because your their boss and they expect you to like them.
