Definition of Diffusion


  1. The act of diffusing, or the state of being diffused; a spreading; extension; dissemination; circulation; dispersion.

Diffusion Quotations

Knowledge is not simply another commodity. On the contrary. Knowledge is never used up. It increases by diffusion and grows by dispersion.
Daniel J. Boorstin

Every one must understand that, whatever be the evil of slavery, it is not increased by its diffusion. Every one familiar with it knows that it is in proportion to its sparseness that it becomes less objectionable. Wherever there is an immediate connexion between the master and slave, whatever there is of harshness in the system is diminished.
Jefferson Davis

Innumerable spirits and souls, when spread out through the same space, do not interfere with each other such that the diffusion of one would affect the diffusion of an infinity of others.
Giordano Bruno

We stand in the shadow of Jefferson who believed that a society founded upon the rule of law and liberty was dependent upon public education and the diffusion of knowledge.
Matt Blunt

The advancement and diffusion of knowledge is the only guardian of true liberty.
James Madison
