This is a lesson. There is no pleasure to be gained without a cost; it may be at the cost of wealth or of time; it may even be at the cost of life. Man, absorbed as he is in the pleasures and comforts of life, thinks very little of this, and goes on until the time comes when it is too late to think of it. Life has been nothing but a captivity to this constant longing for happiness and pleasure, which when it comes he finds himself unable to enjoy.
