Why don’t eclipses occur during any other moon phases besides the new and full moon?
Bad White [126]

Answer:

There's no eclipse at every full moon and new moon because the moon's orbit is inclined to Earth's orbit by about five degrees. Most of the time, the sun, Earth and moon don't line up precisely enough to cause an eclipse.

Explanation:

During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface.

Fechner stated the existence of a functional relationship between body and mind is, in general, not _____
BARSIC [14]

Solution:

Dualists view the mind and the body as two fundamental different “things”, equally real and independent of each other. Cartesian thought, or substance dualism, maintains that the mind and body are two different substances, the non-physical and the physical, and a causal relationship is assumed to exist between them. Physicalism, on the other hand, is the idea that everything that exists is either physical or totally dependent of and determined by physical items. Hence, all mental states are fundamentally physical states. In the current study we investigated to what degree Swedish university students’ beliefs in mind-body dualism is explained by the importance they attach to personal values. A self-report inventory was used to measure their beliefs and values. Students who held stronger dualistic beliefs attach less importance to the power value (i.e., the effort to achieve social status, prestige, and control or dominance over people and resources). This finding shows that the strength in laypeople’s beliefs in dualism is partially explained by the importance they attach to personal values
