Neither life nor happiness can be achieved by the pursuit of irrational
whims. Just as man is free to attempt to survive by any random means, as
a parasite, a moocher or a looter, but not free to succeed at it beyond
the range of the moment - so he is free to seek his happiness in any
irrational fraud, any whim, any delusion, any mindless escape from
reality, but not free to succeed at it beyond the range of the moment nor
to escape the consequences.
-- Ayn Rand, "The Objectivist Ethics," The Virtue Of Selfishness
