Nature has no principles. She makes no distinction between good and evil.

The remark frames “nature” as morally indifferent: the natural world operates by causal processes rather than ethical rules. By saying nature has “no principles” and draws no line between “good and evil,” the speaker rejects the idea that morality is written into the fabric of the universe (or that what is “natural” is therefore “good”). The implication is that ethical judgment is a human construction—arising from society, conscience, or reason—imposed upon an amoral reality. In a broader fin-de-siècle context, the sentiment also pushes back against sentimental or providential readings of nature, emphasizing instead its neutrality toward human suffering and human ideals.
