Moles (1981, p.25) has a straightforward defination of ‘object’: “Etymologically objectum means shoot, something existing outside of ourselves, something put forward with a material caracterist: all that is offered to the eye and affects the senses (Larousse). Philosophers use the term in the sense of what is thought and what is opposed to the being who thinks. The term object, therefore, is constituded by: on the one hand, in terms of resistance to the human being; on the other hand, by the material characteristic of the object. Finally, it also involves the notion of staying connected to inertia In German, Gegenstand expresses the same idea: that is placed against and substantively opposed to humans, thought or reason (objective,objectionable, etc.)”
