This article is a rebuttal to Kevin Smith's ‘Against Homeopathy,’ which was posted on 14 February 2011.1 It contends that his argument rests entirely on the assumption that homeopathic remedies are nothing but placebos. His argumentation is good, but his assumption is false. Evidence is presented to show that the Law of Similars is plausible and that ultradilute remedies do indeed have biological activity.
