Any idea, plan, or purpose may be placed in the mind through repetition of thought.
An invasion of armies can be resisted; an invasion of ideas can not be resisted.[On résiste à l’invasion des armées; on ne résiste pas à l’invasion des idées.]
An idea that is not dangerous is unworthy of being called an idea at all.
An idea ran back and forth in his head like a blind man, knocking over the solid furniture.
An idea is like a cold germ: sooner or later someone always catches it.
An idea is always a generalization, and generalization is a property of thinking. To generalize means to think.[Jede Vorstellung ist eine Verallgemeinerung, und diese gehört dem Denken an. Etwas allgemein machen heißt es denker.]
An idea is a thought. It’s a thought that holds more than you think it does when you receive it. But in that first moment there is a spark.
An ‘idea’ is prepared only on the soil of very hard work, but certainly this is not always the case.[Nur auf dem Boden ganz harter Arbeit bereitet sich normalerweise der Einfall vor. Gewiß: nicht immer.]
Always carry a notebook – you never know when or where inspiration will strike. Plus writing down ideas and thoughts is the best way to progress through life.
All human knowledge begins with intuitions, proceeds from thence to concepts, and ends with ideas.[Alle menschliche Erkenntnis mit Anschauungen an, geht von da zu Begriffen un endigt mit Ideen.]
All great ideas are dangerous.
ALL ACHIEVEMENT, ALL EARNED RICHES, HAVE THEIR BEGINNING IN AN IDEA!
