The quote goes:
So next time someones complains that you have made a mistake, tell them that may be a good thing, because without imperfection, neither you nor I would exist.
I only want the last part:
Without imperfection neither you nor I would exist.
Would I write it like so, or use an ellipsis at the start:
. . . Without imperfection, neither you nor I would exist.
I guess that if I used an ellipsis, it wouldn’t have a capital letter on without, would it?
Instead of an ellipsis, you can use square brackets to indicate light editing in a quotation. They are often used to add minor clarifications or make the quoted text better fit the context, and they're specifically used for the case you're asking about:
Additionally, a small letter can be replaced by a capital one, when the beginning of the original text is omitted for succinctness, for example, when referring to a verbose original.
For example: “[W]ithout imperfection, neither you nor I would exist.”
For me: "... without imperfection, neither you nor I would exist."
