Mr. Spaceship by Philip K. Dick Science Fiction Adventure

<p><strong>The story is set in the distant future where humanity is at war with Yuks an alien life form which does not use mechanical spaceships nor constructions.</strong> Instead it relies on life forms. The war has been going on for a long time and humanity has not been able to come up with a solution against the life-form based ships and mines that the Yuks use. One day a team of researchers led by Philip Kramer decide to build a spaceship which is powered by a human brain. They find the ideal candidate Kramer's old professor a dying man who volunteers to donate his brain to the project. A human brain-controlled spacecraft would mean mechanical perfection. This was accomplished and something unforeseen: a strange entity called . . . Mr. Spaceship!</p>
