The principle of non-contradiction states that "the same attribute cannot belong and not belong:"

    { 1 } - to different subjects at the same time in different respects.
    { 2 } - to the same subject at different times in the same respect.
    { 3 } - to the same subject at the same time in the same respect.
    { 4 } - to different subjects at different times in different respects.
    { 5 } - to the same subject at the same time in different respects.

There is nothing contradictory about Harry being blue-eyed at 10 am, March 17, 1997, and being brown-eyed at a different time. (Don't all babies start out with blue eyes?)

3 is correct!


The principle of non-contradiction states that "the same attribute cannot belong and not belong:"

    { 1 } - to different subjects at the same time in different respects.
    { 2 } - to the same subject at different times in the same respect.
    { 3 } - to the same subject at the same time in the same respect.
    { 4 } - to different subjects at different times in different respects.
    { 5 } - to the same subject at the same time in different respects.

It is contradictory for Harry to be blue-eyed at 10 am, March 17, 1997 and also to be brown-(non-white) eyed at the same time.
