Been reading What Darwin Got Wrong by Jerry Fodor and Massimo Piattelli-Palmarini and they both seem to be saying natural selection is random and not directed like most scientists believe it to be.
Can anyone explain why natural selection is not random?

Douglas J. Futuyma, "Two Critics Without a Clue", Science 328: 5979, pp. 692-69 (7 May 2010)Douglas J. Futuyma said:Fodor and Piattelli-Palmarini show little familiarity with the vast literature on genetic variation, experimental analyses of natural selection, or other topics on which they philosophically expound. They are blithely agnostic about the causes of evolution and apparently uninterested in fostering any program of research. Because they are prominent in their own fields, some readers may suppose that they are authorities on evolution who have written a profound and important book. They aren't, and it isn't.

Can anyone explain why natural selection is not random?
No that would be called human selection, or choice.Can't it be this way?
Natural Selection: selection based on an inherent sense of right and wrong.
If there is random then there is no causal determinism.Can anyone explain why natural selection is not random?
You have chosen two authors who are not even biologists and whose work is discredited.Been reading What Darwin Got Wrong by Jerry Fodor and Massimo Piattelli-Palmarini
:shrug:Jerry Fodor said:The crucial test is whether one’s pet theory can distinguish between selection for trait A and selection for trait B when A and B are coextensive: were polar bears selected for being white or for matching their environment? Search me; and search any kind of adaptationism I’ve heard of. Nor am I holding my breath till one comes along.

Natural selection is what it is. Can you explain what it is? In other words, natural selection is not at dispute here, just a misunderstanding over the value of your authors' work.darryl said:Can anyone explain why natural selection is not random?
If there is random then there is no causal determinism.
Fitness and environment are always predictable? The outcome is always predictable?Natural selection is not random because it is based on fitness in the context of environmental conditions.
Why not?
Determinism- a direct consequence of a non-random worldWe see random behaviour all around us, weather for example seems completely random, human behaviour is another example. But is this behaviour truly random? The answer is a big NO. Every physical phenomenon around us is at best unpredictable ie. human beings are unable to predict it (due to a large no. of factors,accuracy,etc.). However, just because we are unable to predict an event does not mean that it would not follow a predefined path. All events are a direct consequence of a another event or a set of events.Thus no event is truly random or spontaneous,ie. it could be influenced by a multitude of other events or maybe all other events in the universe but it didn't just happen without any cause. Also see articles on Causality (physics), Deterministic system (philosophy)
As seen above there are no truly random events in the universe. Thus every event can be traced back to another event (or a set of events). Each of the older events are themselves a consequence of prior events.Thus every event can be traced back to the state of the universe at its beginning ie. the Big Bang. Thus, we can conclude that all events after the big bang are simply following a predetermined path.
Natural selection is what it is. Can you explain what it is?
http://bioap.wikispaces.com/ch22+collaboration :Artificial selection (or selective breeding) describes intentional breeding for certain traits, or combination of traits. The term was utilized by Charles Darwin in contrast to natural selection, in which the differential reproduction of organisms with certain traits is attributed to improved survival or reproductive ability (“Darwinian fitness”). As opposed to artificial selection, in which humans favor specific traits, in natural selection the environment acts as a sieve through which only certain variations can pass.
Artificial selection is the intentional breeding of certain organisms to produce the desired traits/characteristics. This can lead to different species being created, while others die off. For example, farmers often interbreed multiple populations of one crop to produce that crop with the characteristics that they want.
Natural selection is the the result of “survival of the fittest.” “Fittest” actually has little to do with physical or mental fitness and completely to do with fitting into an environment. Organisms that are more “fit” survive, reproduce, and perpetuate the genes that made them survive in the first place. Those organisms that are not “fit” die, along with the traits that were no help to them.
No that would be called human selection, or choice.
Natural selection does not derive from humans, but from nature.
Which is why it's called "natural".
