No, I don't think all ideas from past writers are outdated. Many classic books still have a lot to offer. For example, the works of Shakespeare or Jane Austen give us insights into human emotions and social interactions that are still very much applicable today. These books help us understand different aspects of human nature and societal structures, which haven't really changed all that much over the centuries.

Yes, I think some ideas from books in the past might be considered outdated today. For instance, the views on race, gender, or science presented in some older works do not align with modern understandings and values. Society has evolved, and with it, our perspectives on many issues have changed. This can make some of the ideas expressed in older literature seem irrelevant or incorrect by today's standards.

It really depends on the type of ideas and the context in which they were written. Some scientific theories from the past have been disproven and replaced by more accurate models. However, themes in literature that explore human emotions and experiences can still be very relevant. Readers today might find new meanings or interpretations in old texts based on current societal contexts.
