AS the cosmological argument for the existence of God has survived seven centuries and is still debated in philosophical circles, I think it is rather harsh of Phil Hinton to call it "ill-informed" (You Say, September 4).

I was already aware that quantum physics has posed some problems for the cosmological argument, namely in bringing to question the principal previously fundamental to existing scientific laws that all things require a course.

However, there are a number of different interpretations of the findings of quantum physics, some of which would harmonise with conventional physics.

As can be detected in the tone of Mr Hinton's concluding comment, a good deal of the conclusions of quantum physics are at best speculative, as a result of the difficult of observing particles at a sub-atomic level.
