I am trying to find information on the criticism that Immanuel Kant had for previous ethical theories. Any suggestions...I've found a few places online but I don't understand the language.

Kant isn't easy to understand, but I suggest you work at trying to understand these sources.

To find information on Immanuel Kant's criticism of previous ethical theories, you can follow these steps:

1. Start with a general search on search engines like Google or Bing. Enter keywords such as "Immanuel Kant criticism of previous ethical theories."
2. Look for reliable sources such as academic websites, philosophy journals, or reputable encyclopedias. Websites ending in .edu or .org are often good sources of information.
3. In your search results, you may come across scholarly articles, books, or online resources that discuss Kant's critique of previous ethical theories. These sources are likely to provide more in-depth analysis and explanations, but they may also use specialized academic language.
4. If you find academic articles or books, check if there is an abstract or summary that provides a concise overview of the content. This can help you decide if the source is relevant to your needs.
5. If the language in the sources you find is difficult to understand, try breaking down the sentences or paragraphs and looking up specific terms or phrases that are causing confusion. Philosophy can often involve complex concepts and arguments, so it is normal to encounter unfamiliar language.
6. Consider consulting introductory books or articles on Kantian ethics to gain a basic understanding of the subject before delving into more advanced or specialized works.

It is important to note that understanding philosophical texts can sometimes be challenging, even for those with some background knowledge. Don't be discouraged if you find the language difficult at first. With perseverance and additional study, the concepts will become clearer.
