impossible

IMPOSS'IBLE, a. [L. impossibilis; in and possibilis, from possum, to be able.]

1. That cannot be. It is impossible that two and two should make five, or that a circle and a square make five, or that a circle and a square should be the same thing, or that a thing should be, and not be at the same time.

2. Impracticable; not feasible; that cannot be done.

With men this is impossible; but with God all things are possible. Matt.19.

Without faith it is impossible to please God. Heb.11.

There are two kinds of impossibilities; physical and moral. That is a physical impossibility, which is contrary to the law of nature. A thing is said to be morally impossible, when in itself it is possible,but attended with difficulties or circumstances which give it the appearance of being impossible. [See Possible, Practicable and Impracticable.]
