The powers of the mind should be concentrated and the mind turned back upon itself; as the darkest places reveal their secrets before the penetrating rays of the sun, so will the concentrated mind penetrate its own innermost secrets.
If the genius of invention were to reveal to-morrow the secret of immortality, of eternal beauty and youth, for which all humanity is aching, the same inexorable agents which prevent a mass from changing suddenly its velocity would likewise resist the force of the new knowledge until time gradually modifies human thought.
For the secret of man's being is not only to live but to have something to live for. Without a stable conception of the object of life, man would not consent to go on living, and would rather destroy himself than remain on earth, though he had bread in abundance.
It is odd how, when you have a secret belief of your own which you do not wish to acknowledge, the voicing of it by someone else will rouse you to a fury of denial.
I have complete confidence in Secret Service. These guys and gals are unbelievably professional. They know what they’re doing and I basically do what they tell me to do. Now, sometimes I’m the first one to admit that it chafes a little bit being inside this bubble. It’s the hardest adjustment of being president, not being able to just take a walk.
