Suppose you could be hooked up to a hypothetical 'experience machine' that, for the rest of your life, would stimulate your brain and give you any positive feelings you desire. Most people to whom I offer this imaginary choice refuse the machine. It is not just positive feelings we want: we want to be entitled to our positive feelings.

Positive emotion alienated from the exercise of character leads to emptiness, to inauthenticity, to depression, and, as we age, to the gnawing realization that we are fidgeting until we die.

The belief that we can rely on shortcuts to happiness, joy, rapture, comfort, and ecstasy, rather than be entitled to these feelings by the exercise of personal strengths and virtues, leads to legions of people who, in the middle of great wealth, are starving spiritually.
