Sentiment Inc. by Poul Anderson: The way we feel about another person or about objects is often bound up in associations that have no direct connection with the person or object, at all. Often, what we call a "change of heart" comes about sheerly from a change in the many associations which make up our present viewpoint. Now, suppose that these associations could be altered artificially, at the option of the person who was in charge of the process....

Hawk Carse by Harry Bates: One of the spectacular exploits of Hawk Carse, greatest of space adventurers.
