Our task must be to free ourselves...by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty.  Albert Einstein quotes To be a well-flavored man is the gift of fortune, but to write or read comes by nature. William Shakespeare quotes A friend might well be reckoned the masterpiece of nature. Ralph Waldo Emerson quotes This is the true nature of home -- it is the place of Peace; the shelter, not only from injury, but from all terror, doubt and division. John Ruskin quotes Practical wisdom is only to be learned in the school of experience. Precepts and instruction are useful so far as they go, but, without the discipline of real life, they remain of the nature of theory only. Samuel Smiles quotes Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure, or nothing. Helen Keller quotes If thou live according to nature, thou wilt never be poor; if according to the opinions of the world, thou wilt never be rich. Seneca quotes There are three principal means of acquiring knowledge. . . observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Denis Diderot quotes Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common. Denis Diderot quotes It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness where only an approximation is possible.
