The soul of God is poured into the world through the thoughts of men.
Ralph Waldo Emerson

Albert Einstein
The history of thought may be summed up in these words: it is absurd by what it seeks and great by what it finds
Paul Valery
Men fear thought as they fear nothing else on earth -- more than ruin -- more even than death.... Thought is subversive and revolutionary, destructive and terrible, thought is merciless to privilege, established institutions, and comfortable habit.
Bertrand Russell
Thought is great and swift and free, the light of the world, the chief glory of man.
Bertrand Russell
No one on earth has lived through the exact same experiences you have, and no one thinks the exact same thoughts you do.
Steve Pavlina

Steve Pavlina
High thoughts must have high language.
Aristophanes
If you can't read and write you can't think. Your thoughts are dispersed if you don't know how to read and write. You've got to be able to look at your thoughts on paper and discover what a fool you were.
Ray Douglas Bradbury
Don't you know that every time we meet the thoughts of the final parting will become more painful? Don't you feel that every interview makes us dearer to each other than the last?
Anne Bront
Thou must be true thyself, If thou the truth wouldst teach; Thy soul must overflow, if thou Another's soul would'st reach! It needs the overflow of heart To give the lips full speech. Think truly, and thy thoughts Shall the world's famine feed; Speak truly, and each word of thine Shall be a fruitful seed; Live truly, and thy life shall be A great and noble creed.
Horatius Bonar
