Elizabeth Sanderson Haldane CH JP (/ˈhɔːldeɪn/; 27 May 1862 – 24 December 1937) was a Scottish author, biographer, philosopher, suffragist, nursing administrator, and social welfare worker.

She was intimate with royalty such as Queen Alexandra[7] and was a personal friend of literary figures such as Matthew Arnold and George Meredith.

Descartes' first reflections that winter at Neuberg, when free from cares and passions he remained the whole day in his well-warmed room, gave the colour to the remainder of his life.

The first conclusion the young man came to was this: that seldom does a work on which many persons have been employed attain to the same perfection as that which has been carried out by one single directing mind: this we see clearly in buildings, or in cities which have grown from villages.

And with nations the case is similar: civilisation is a growth which has largely come about through the necessity bred of suffering, while the direction of some wise legislation or the ordinances of God must be incomparably superior.

Learning has suffered in this way; the sciences have gradually been drawn far from the truth which a sensible man, using his natural and unprejudiced judgment, would gather from his own experience.
