I'm trying to say that all humans on planet earth are social creatures, without using plural form.
A human is a social creature.
The human is a social creature.
Human is a social creature.
What is the best way?
Last one is probably wrong. I wondered whether it is possible to refer to the word "human" as one would refer to an uncountable noun.
As, for example, with the word "time" which can be countable/uncountable. As in sentence:
Thank you for your time.
A new question has risen whether there should be an article preceding "other human being" in the sentence following the first one.
The human is a social creature. Sometimes, interaction with other human being can become overly emotional and in such state we have tendency to act impulsively while not realizing that some of our decisions made can become permanent—beyond possibility of repair.
The question now is whether there should be an article before other human being.
Best Answer
This is the best construction of the three. It uses "the human" in the sense of "the class of things known as human". Coincidentally, this is basically the same answer I just gave here.
The first sentence also could work, if it is crystal clear from context that you are speaking generally about the characteristics of all humans. The third sentence is ungrammatical.
