Previously I have posted about the misconception that if something appears to be random then it cannot have purpose.
Paul La Montagne recently pointed out to me that true randomness actually requires design. It is very hard to produce "random numbers". Mathematicians and computer scientists work very hard to design random number generators.
Hence, if we observe something that appears to be "random", i.e. has no underlying pattern or order we are not justified in claiming that it has not been designed. There could be a deep and profound and underlying order to it.
