"The truth is that all these three - duty, remoteness and causation - are all devices by which the courts limit the range of liability for negligence . it I not even consequences of a wrongful act which is subject of compensation. the law has to draw a line somewhere. sometimes it is not by limiting the range of the persons to whom duty is owed.sometimes it is one by saying that there is a break in the chain of causation. at other times it is done by saying that the consequence is too remote to be a head of damage .All these devices are useful in their way. But ultimately it is a question of policy for the judges to decide."

supporting your arguments with reference to the relevant cases and wider academic materials. critically evaluate the above statement made by lord denning in lamb v Camden London and explain how far you agree with this approach to the application of the principles of causation.
