B. H. Liddell Hart Ideas Quotations

For the spread and endurance of an idea the originator is dependent on the self-development of the receivers and transmitters.

...regrettable as it may seem to the idealist, the experience of history provides little warrant for the belief that real progress, and the freedom that makes progress possible, lies in unification. For where unification has been able to establish unity of ideas it has usually ended in uniformity, paralysing the growth of new ideas. And where the unification has merely brought about an artificial or imposed unity, its irksomeness has led through discord to disruption.

Opposition to the truth is inevitable, especially if it takes the form of a new idea, but the degree of resistance can be diminished- by giving thought not only to the aim but to the method of approach. Avoid a frontal attack on a long established position; instead, seek to turn it by flank movement, so that a more penetrable side is exposed to the thrust of truth. But, in any such indirect approach, take care not to diverge from the truth- for nothing is more fatal to its real advancement than to lapse into untruth.

The only thing harder than getting a new idea into the military mind is to get an old one out.
