Principals of individual freedom: the basic assumptions behind "what is personal freedom"

Helga, извините за вопрос..но, чем Вас не устраивают слова "принципы индивидуальной свободы"?... вроде бы, не такие уж и сложные...

I suspect that most of your difficulty lies is the difference between the words principal and principle. The quotation you reproduce should use the word principle. If, after looking up the relevant words, you still have trouble understanding the sentence, please feel free to message me with your question.

it's not "principals" but to be corrected as "principles" Principles of individual freedom can be understood as "a basic generalization or truth or law or assumption that is accepted as true and that can be used as a basis for reasoning or conduct"
