Strictly speaking, there is no such thing as fortune, chance, or accident. All things are held together by invariable laws. Every event takes place in accordance with law. Uniformity of law is the condition and presupposition of all our thinking. The very idea of an event that has no cause is a contradiction in terms to which no reality can correspond, like the notion of two mountains without a valley between; or a yard stick with only one end. Relatively to us, and in consequence of the limitation of our knowledge, an event is a result of chance or fortune when the cause which produced it lies beyond the range of our knowledge. What we cannot anticipate beforehand and what we cannot account for afterward, we group together into a class and ascribe to the fictitious goddess Fortune; as children attribute gifts at Christmas which come from unknown sources to Santa Claus. In reality these unexplained and unanticipated events come from heredity, environment, social institutions, the forces of nature, and ultimately from God. These things which project themselves without warning into our lives, often have most momentous influence for good or evil over us; and the proper attitude to take toward this class of objects is worthy of consideration by itself. THE DUTY. +The secret of superiority to fortune.+--Some things are under our control; others are not. It is the part of wisdom to concentrate our thought and feeling on the former; working with utmost diligence to make the best use of those things which are committed to us in the regular line of daily duty, and treating with comparative indifference those things which affect us from without. What we are; what we do; what we strive for;--these are the really important matters; and these are always in our power. What money comes to us; what people say about us; what positions we are called to fill; to what parties we are invited; to what offices we are elected, are matters which concern to some extent our happiness. We should welcome these good things when they come. But they affect the accidents rather than the substance of our lives. We should not be too much bound up in them when they come; and we should not grieve too deeply when they go. We should never stake our well-being and our peace of mind on their presence or their absence. We should remember that "The aids to noble life are all within."
