Side 1: Science is unlimited. There is no end to what scientists will be able to discover, no bound to the endless frontier, no topic that science will not eventually be able to explain.

Side 2: Science is inherently limited. There are areas that science will never be able to touch, much less find answers to. For example, the realm of emotion (love, despair, hope), or the meaning of life. Moreover most of the great discoveries of science have already been made, what's left is the mop-up stage.
