Human nature is not nearly as bad as it has been thought to be... In fact it can be said that the possibilities of human nature have customarily been sold short.

Light is white: dark is black.

To me, grey is the welcome and only possible equivalent for indifference, noncommitment, absence of opinion, absence of shape. But grey, like formlessness and the rest, can be real only as an idea, and so all I can do is create a colour nuance that means grey but is not it. The painting is then a mixture of grey as a fiction and grey as a visible, designated area of colour.

Human nature is imperfect.

Human nature is not a machine to be built after a model, and set to do exactly the work prescribed for it, but a tree, which requires to grow and develop itself on all sides, according to the tendency of the inward forces which make it a living thing.

everybody has a light and a dark side, and neither can exist without the other.

There is not one human nature. There is not some uniform and unchanging way that everybody is and how everybody sees the world. Human nature has different meanings in different times and for different classes and groups in society.

I am trying to describe the nature of humans, not prescribe their morality. That something is natural does not make it right.

Such is the influence which the condition of our own thoughts, exercises, even over the appearance of external objects. Men who look on nature, and their fellow-men, and cry that all is dark and gloomy, are in the right; but the sombre colours are reflections from their own jaundiced eyes and hearts. The real hues are delicate, and need a clearer vision.

Human nature is pretty well balanced; for every lacking virtue there is a rough substitute that will serve at a pinch — as cunning is the wisdom of the unwise, and ferocity the courage of the coward.

Such are the laws of nature and balance. An if we look at the darkness growing in the world today, we have to realize that this means there is equal light growing.

Nature is reflected in human face. All the visible and invisible beauty around us is a manifestation of human nature, decorated with "Hope and Love".

The world is not black and white. More like black and grey.

What we call human nature in actuality is human habit.
