Document Summary

When 2 claims conflict, they simply cannot be both true, at least one of them has to be false. It"s (cid:373)y (cid:271)irthday today; it"s (cid:374)ot (cid:373)y (cid:271)irthday today. The door is ope(cid:374); the door is(cid:374)"t ope(cid:374) (cid:862)if a (cid:272)lai(cid:373) (cid:272)o(cid:374)fli(cid:272)ts (cid:449)ith other (cid:272)lai(cid:373)s (cid:449)e ha(cid:448)e good reaso(cid:374) to a(cid:272)(cid:272)ept, (cid:449)e ha(cid:448)e good grou(cid:374)ds for dou(cid:271)ti(cid:374)g it(cid:863) Contradiction: one of the two statements is true, the other must be false. Inconsistent: both of the statements cannot be true. I had lunch in paris, france today and i also had lunch in london, england today (cid:862)if a (cid:272)lai(cid:373) (cid:272)o(cid:374)fli(cid:272)ts (cid:449)ith our (cid:271)a(cid:272)kgrou(cid:374)d i(cid:374)for(cid:373)atio(cid:374) (cid:449)e ha(cid:448)e good reaso(cid:374) to dou(cid:271)t it(cid:863) If a (cid:272)lai(cid:373) (cid:272)o(cid:374)fli(cid:272)ts (cid:449)ith our (cid:271)a(cid:272)kgrou(cid:374)d k(cid:374)o(cid:449)ledge, that"s a reaso(cid:374) to reje(cid:272)t it. E. g. some babies can bench press 500lbs this claim goes against all that we know about babies. In other words it is common knowledge that babies obviously cant bench press 500lbs.
