Imagine we have two names, X and Y, which describe the same object.

If X and Y are identical in every possible way, and therefore X=Y, is

X is like Y.

a true statement?

    It is not false, but you aready said they are the same, not similar, which is what "is like" means. Apr 28 '20 at 23:23
  • What exactly do you mean? If X is red and Y is round, we can say that they both describe aspects of a red ball, but they won't be equal to each other. And to say that something is like itself would be bizarre. I am not like myself, I am myself. Apr 29 '20 at 0:07
  • Your question would benefit from concrete examples, rather than this abstract consideration.

  • @JasonBassford X and Y are not properties, they are names/labels. For example, X = "human" and Y = "person". Apr 29 '20 at 0:39

If something is identical (X==Y) then it is necessarily alike (but more than that)
If something is alike, it is not necessarily identical.

X equals / is identical to Y is thus a stronger / stricter statement (than alike)

So, as Weather Vane said in his comment, "X and Y are alike" is not a false statement, but it is one you would not say, as you already said (or if you haven't, you should say [because it provides more information]) that "X and Y are identical".

Saying "X is like Y" after saying they are identical actually takes away from the strength of the identical statement (and is confusing because why would you partially/potentially negate what you just said).
