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.
