THESE implies "nearness" or proximity to you, as though it were a collection of things in your hand, or near to your hand, or things that you reference mentally, such as a list of Abstract Conceptions that you refer to. THOSE implies distance from you. It can also apply to a list of Abstract Conceptions that you refer to as "distant" ideas. Example: These candies are better than those candies. These books are better than those books. These things, Good, Evil, and Integrity are moral values. Those things are material objects, and do not qualify as Abstract Conceptions. These ideas are plausible; but those ideas are implausible. .
