Fisher campaigned for the abolition of illegitimacy, and was a staunch advocate of birth control, publishing and distributing free literature on contraception.

[6] He was considered among the leading individualists, alongside figures such as Auberon Herbert, Wordsworth Donisthorpe, Joseph Hiam Levy, and Henry Seymour.

[8] His platform included "voluntary taxation, no compulsory education, liberty for Ireland with no government, the abolition of professional monopolies, and female freedom".

[3][1] An example of this can be seen in a letter Fisher wrote to The Phonographic Magazine, in which he advised language reformers to: "selekt the simplest spelling praktikabel for any word when in doubt az to the kustomary form".

[9] In addition to contributing regularly to publications such as Liberty, Fisher edited a paper called The Free Thought Record.
