Final answer:
Yes, philosophers such as Ludwig Gumplowicz and Machiavelli have discussed the concept of a state of constant war, although these views are not widely accepted.
Step-by-step explanation:
Yes, there have been philosophers who argued for a state of constant war as an ideal state. One such philosopher is Polish-Austrian sociologist Ludwig Gumplowicz, who expanded on Marx's ideas by suggesting that war and conquest are the bases of civilizations. He believed that cultural and ethnic conflicts lead to states being defined by a dominant group with power over other groups.
Another philosopher who discussed the role of war in society is Machiavelli. While he did not argue for a constant state of war, he emphasized the importance of a strong military and the willingness to use force in order to maintain power.
It is important to note that these arguments do not represent mainstream or widely accepted views, and they are often seen as extreme or controversial.
