"The grand, leading principle, towards which every argument . . . unfolded in these pages directly converges, is the absolute and essential importance of human development in its richest diversity."This description by Wilhelm von Humboldt of his purpose in writing "The Limits of State Action" animates John Stuart Mill's "On Liberty" and serves as its famous epigraph. Seldom has a book spoken so dramatically to another writer. Many commentators even believe that Humboldt's discussion of issues of freedom and individual responsibility possesses greater clarity and directness than Mill's.

"The Limits of State Action, " by "Germany's greatest philosopher of freedom," as F. A. Hayek called him, has an exuberance and attention to principle that make it a valuable introduction to classical liberal political thought. It is also crucial for an understanding of liberalism as it developed in Europe at the turn of the nineteenth century. Humboldt explores the role that liberty plays in individual development, discusses criteria for permitting the state to limit individual actions, and suggests ways of confining the state to its proper bounds. In so doing, he uniquely combines the ancient concern for human excellence and the modern concern for what has come to be known as negative liberty.J. W.

Linguistic Variability and Intellectual Development, Wilhelm von Humbolt's most famous work, was published by his brother Alexander posthumously, in 1836. It promptly established itself as a classic in the philosophy of language and has held that position ever since. With many examples from a vast multitude of languages, from Sanskrit to Delaware Indian, the author shows how character and structure of a language expresses the inner life and knowledge of its speakers and how their intellectual development is in turn shaped by their language.
