The chief cause of unhappiness in married life is that people think that marriage is sex attraction, which takes the form of promises and hopes and happiness - a view supported by public opinion and by literature.

The march of humanity, springing as it does from an infinite multitude of individual wills, is continuous.

What a strange illusion it is to suppose that beauty is goodness.

Spring is the time of plans and projects.
