Pim: That's where we disagree. Science does not claim to know the
truth.
Keithp: Then what does science claim to know?
Pim: Science describes observations, makes theories and hypothesis but
does not
claim to know the truth.
But my question was What is it that science claims to "know"? You keep
speaking of our knowledge being increased as a result of science, yet
deny that science makes any truth claims. Traditionally, knowledge has
been defined as justified true belief. In other words, to know
something is to hold beliefs that correspond to what is actually the
case (i.e. true) and to have epistemological warrant for those beliefs.
Similarly, when we claim to understand an object or process, we are
claiming to possess a certain degree of knowledge about it. Perhaps it
would help our communication if you would define knowledge as you are
using the term. Thanks
