The attitude of unhappiness is not only painful, it is mean and ugly. What can be more base and unworthy than the pining, puling, mumping mood, no matter by what outward ills it may have been engendered? What is more injurious to others? What less helpful as a way out of the difficulty? It but fastens and perpetuates the trouble which occasioned it, and increases the total evil of the situation. At all costs, then, we ought to reduce the sway of that mood; we ought to scout it in ourselves and others, and never show it tolerance.
In science men have discovered an activity of the very highest value in which they are no longer, as in art, dependent for progress upon the appearance of continually greater genius, for in science the successors stand upon the shoulders of their predecessors; where one man of supreme genius has invented a method, a thousand lesser men can apply it.
Human life in common is only made possible when a majority comes together which is stronger than any separate individual and which remains united against all separate individuals. The power of this community is then set up as right in opposition to the power of the individual, which is condemned as brute force.
