Two conflicting pictures of us in the world . Science people composed of particles of matter behave in accordance with the laws of physics. Particles existed before you did; laws particles obey not created by you, just result of the properties of matter. Therefore it is not up to you what you do, or what your body does. There are morally good and morally evil choices. Praised for good choices, blamed for bad choices. It is true that every now and then you do something that has a bad result. Accidentally killing someone, a killer killing someone, telling the judge the laws of nature made him do it. Determinism every event is caused by a past event caused by natural laws. Indeterminism some events, some human actions, are not caused by anything (events are random) Libertarianism part 1 if determinism is true, we aren"t responsible for any actions, nature is, no free will.
