I believe the answer is: Common underlying principles
Common underlying principles refer to the standard set of mind that we commonly use to approach a certain problem.
If an individual is used to look everything that happen in his/life postiively, that individual would less likely to develop suicidal thought regardless of his/her problems.
The ~unequal~ statuses of different individuals in a society. for example, a doctor has a higher social status than a janitor working at the same hospital. the doctor might be awarded for his work, while the janitor is mostly ignored. the doctor may also have come from a fairly wealthy family and received a good education, while the janitor may have had economic disadvantages and a poor quality education. so the doctor and the janitor are socially unequal. social inequality is very closely connected to economic inequality, so if you ever see the phrase "socio-economic inequality," that's why.
Spencer trusted that exclusive the fittest society would get by after some time, prompting general up reviewing of the world overall. Herbert Spencer was a noteworthy figure in the scholarly existence of the Victorian time. He was one of the vital advocates of developmental hypothesis in the mid nineteenth century, and his notoriety at the time matched that of Charles Darwin.
