Act in such a way that you treat humanity, whether in your own person or in the person of another, always at the same time as an end and never simply as a means.

Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end.

Treat people as an end, and never as a means to an end

Treat others as you would be treated. Devote yourself to that, for there’s no more direct approach to Humanity.

Human beings are never to be treated as a means but always as ends.

Treating a being as an end in itself means respecting the value of what makes it such an end. After we see that this value resides in rational nature, we see it implies that, at least in general, rational beings should not be subjected to deception or coercion. Instead, we should seek to harmonize our strivings with those of other rational beings toward their ends.

Act toward others as you would act toward a part of your own self.

Look to be treated by others as you have treated others.

I feel that human beings should treat human beings like human beings.

Every being is an end. In other words, every being is to be taken into account in determining the ends of conduct. This is the only consistent outcome of the ethical process which is in course of evolution on the earth. This world was not made and presented to any particular clique for its exclusive use or enjoyment. The earth belongs, if it belongs to anybody, to the beings who inhabit it—to all of them. And when one being or set of beings sets itself up as the sole end for which the universe exists, and looks upon and acts toward others as mere means to this end, it is usurpation, nothing else and never can be anything else, it matters not by whom or upon whom the usurpation is practised.

In everything one must consider the end.

Man, and in general every rational being, exists as an end in himself, not merely as a means for arbitrary use by this or that will: he must in all his actions, whether they are directed to himself or to other rational beings, always be viewed at the same time as an end.

Consider everything belonging to another as if it were your own, and so treat it.

We should strive to treat each other with common Human Decency
