The analyses of a text #3

The protagonist, Philip, who has a club-foot innately, got into a boarding school.

But he had grown very self-conscious. The new-born child does not realise that his body is more a part of himself than surrounding objects, and will play with his toes without any feeling that they belong to him more than the rattle by his side; and it is only by degrees, through pain, that he understands the fact of the body. And experiences of the same kind are necessary for the individual to become conscious of himself; but here there is the difference that, although everyone becomes equally conscious of his body as a separate and complete organism, everyone does not become equally conscious of himself as a complete and separate personality. The feeling of apartness from others comes to most with puberty, but it is not always developed to such a degree as to make the difference between the individual and his fellows noticeable to the individual. It is such as he, as little conscious of himself as the bee in a hive, who are the lucky in life, for they have the best chance of happiness: their activities are shared by all, and their pleasures are only pleasures because they are enjoyed in common; you will see them on Whit-Monday dancing on Hampstead Heath, shouting at a football match, or from club windows in Pall Mall cheering a royal procession. It is because of them that man has been called a social animal.

1. I'd like to know if "fact" means "truth."
2. I'd like to know if "such as" means "like."
3. And I'd like to know if the blue adjectival clause modifies "he."
Thank you in advance for your help.
