What is colouring material?

Famous quotes containing the words material and/or colouring:

    To-day ... when material prosperity and well earned ease and luxury are assured facts from a national standpoint, woman’s work and woman’s influence are needed as never before; needed to bring a heart power into this money getting, dollar-worshipping civilization; needed to bring a moral force into the utilitarian motives and interests of the time; needed to stand for God and Home and Native Land versus gain and greed and grasping selfishness.
    Anna Julia Cooper (1859–1964)

    Every philosophy is tinged with the colouring of some secret imaginative background, which never emerges explicitly into its train of reasoning.
    Alfred North Whitehead (1861–1947)
