The previous statements make the following assumptions:

A.) That it is in fact an egg (as definition dictates and not simply something that appears as one say a Fabergé egg or unusually shaped hollow rock)

B.) That it is not old, preserved, or otherwise now (or perhaps has been) placed in new and possibly unsuitable conditions for its respective biological hatching process

Z has yet to be explicitly defined though a reader can infer this is the idea that a creature either will or will not be hatched?

1.) Sure. Not all eggs follow the respective biological hatching process for a multitude of reasons.

2.) Considering all variables are in either constant or continual reference to current or potential states of a single object, both actual and hypothetical, I suppose?

3.) Thought, in general? People have written entire books on this so. I want to say, both? I think, lol.

4.) What isn't thought? Mayhaps.. thought is an observation or statement, or series of observations or statements one believes is unheard and is made under the assumption it will not be responded to?

Wisdom is one's capacity to judge based on one's prior knowledge.

Philosophy is akin to wisdom. In philosophy we can make an association between X and Y, and formulate Z using our intelligence (knowledge associated with the subject; i.e. intel).

Z may be unstable but if we want to make it stable it would be a jump from pure-philo to science.

To me wisdom is knowing that Religion and Mysticism are not based on reason. They are based on the belief, faith and mystical experiences.

Philosophy is based on reason and logic. Therefore we can debate on all the topics in critical way in philosophical discussion.

In Religion and Mysticism, we cannot debate the topics as we do in Philosophy in critical way. The distinction is clear, and understanding that difference, to me is wisdom.

"Mysticism is entirely emotional, entirely made up of subtle, incommunicable sensations, which are even more incapable of verbal expression and logical definition than are such things as sound and color and line." -pp. 19 Esotericism and Modern Thought by P.D. Ouspensky
