The leading Fabians held different versions of permeation: Shaw saw permeation in terms of weaning the Radicals away from the Liberal party, so he favoured an independent party; Webb defined permeation in terms of the giving of expert advice to a political elite without any need for a new party. These varieties of permeation can be traced in the individual and collective actions of the Fabians, and, in particular, in their attitude to the formation of the Independent Labour party (I.L.P.). The Fabians did not simply promote the I.L.P. nor did they simply oppose the I.L.P.
