A radical skeptic might be willing to doubt which of the following

As a radical skeptic, one may be willing to doubt or question a wide range of beliefs and claims. Radical skepticism is a philosophical position that involves questioning the possibility of knowledge and the reliability of perception, experience, and language. Therefore, a radical skeptic might be willing to doubt any of the following:

1. External reality: They may doubt the existence of an external world and question whether everything is simply an illusion or a deception.

2. Sense perception: They may doubt the accuracy and reliability of our senses, such as questioning whether what we see, hear, touch, taste, or smell truly corresponds to the external reality.

3. Knowledge and truth: They may doubt the possibility of having true knowledge and argue that all claims are uncertain and subject to doubt.

4. Causality: They may doubt the connection between cause and effect, questioning whether we can really know if one event causes another.

5. The existence of a higher power: They may doubt the existence of any gods or higher powers, challenging religious and spiritual beliefs.

6. Logic and reason: They may doubt the reliability of logical reasoning and argumentation, suggesting that even seemingly valid arguments may be flawed.

It's important to note that radical skepticism is an extreme philosophical position, and few people truly adhere to it in every aspect of their lives. Nevertheless, exploring these doubts and questioning established beliefs can be a valuable exercise in critical thinking.
