Mid-summer ... when the alchemy of Nature transmutes the sylvan landscape to one vivid and almost homogeneous mass of green; when the senses are well-nigh intoxicated with the surging seas of moist verdure and the subtly indefinable odours of the soil and the vegetation. In such surroundings the mind loses its perspective; time and space become trivial and unreal, and echoes of a forgotten prehistoric past beat insistently upon the enthralled consciousness.
Two things fill the mind with ever new and increasing admiration and awe, the oftener and more steadily we reflect on them: the starry heavens above me and the moral law within me.

Nature is a mutable cloud which is always and never the same.
This is what you shall do: Love the earth and sun and the animals, despise riches, give alms to every one that asks, stand up for the stupid and crazy, devote your income and labor to others, hate tyrants, argue not concerning God, have patience and indulgence toward the people.

Day was breaking at Plashwater Weir Mill Lock. Stars were yet visible, but there was dull light in the east that was not the light of night. The moon had gone down, and a mist crept along the banks of the river, seen through which the trees were the ghosts of trees, and the water was the ghost of water. This earth looked spectral, and so did the pale stars: while the cold eastern glare, expressionless as to heat or colour, with the eye of the firmament quenched, might have been likened to the stare of the dead.
Nature does nothing without a purpose. In children may be observed the traces and seeds of what will one day be settled psychological habits, though psychologically a child hardly differs for the time being from an animal.
