The Natural attitude is a perspective or way of everyday seeing whereby, for example, when we see a cat, seeing it is to also see a meaningful structure that is inclusive of a wider horizon of possible cats black, spotted, green-eyed... big, small, healthy, sick, four-legged and three legged, etc. To seethe cat is to presuppose an empirical foreground upon a background of possible cats unified by the structure 'cat'.
The Natural attitude is a term that explains how, in ordinary waking experience, we take it for granted that the world around us exist independently of both us and our consciousness of it. We share an implicit belief in the independent existence of the world which permeates and informs our everyday experience.
The Natural attitude has a non-theoretical nature. It is, however, only when we come to recognize the natural attitude for what it is, that we break with it and adopt the philosophical, theoretical attitude.
The Natural attitude is our everyday perspective which usually goes unnoticed as a perspective whereby, for example, when we leave our house in the morning, we take the objects we see around us as simply real, factual things this tree, neighboring buildings, cars, et cetera.
The Natural attitude is the attitude of experience (experience simply being that which is prior to all the inferential, scientific, thinking.).
The Natural attitude is an empirical attitude from which I see my ego as fundamentally separate from the world around me, a world that is obviously already here, quite apart from me, and which has no relation to me other than as my context and the container for other objects of interest to me.
The Natural attitude is ordinary waking experience where we take it for granted that the world implicitly appears independently from us.
The Natural attitude is the attitude of all of the empirical sciences. It posits the independent existence of the world and so must be 'put out of play' by the phenomenologist.
