Is Knowledge Fallible?

My question is about the definition of knowledge as used by philosophers in the area of epistemology.

I am wondering if knowledge implies certainty. In other words, if you are not certain of something, can you know that thing, or must you be certain in order to know it?

If knowledge does not imply certainty, what term would be used to refer to knowing something for certain?

  • Hardly a new question. Did you check other questions with the epistemology tag, like What is the difference between knowledge and belief?, Is Knowledge Fallible? or basic introductions to epistemology? Because this question is answered everywhere.

  • @iphigenie That wasn't really helpful... I'm not asking about belief, JTB is contested (indicating the term 'knowledge' is not defined by it), and saying "go read a book" doesn't seem to be in line with the intentions of this site.

  • What is in line with the intentions of this site is doing one's homework and sharing one's research. Your question lacks that. I didn't mean to be rude. I meant that maybe you could tell us what you've read or what you know or read some basic introduction first. Always helpful: The Stanford Encyclopedia of Philosophy

  • @iphigenie Again, not helpful. The link you provided does not define the term 'knowledge'; it merely discusses how it is obtained. This site is not primarily for sharing research, but for Q&A. If I knew the answer to my question I wouldn't need to ask it. Since you are so new to the SE site, I would suggest leaving criticisms of the format of questions to the mods.

    @iphigenie If the answer is so straightforward, why not post it? I'm eager to get an answer to this.
