阿尔伯特·爱因斯坦（Albert Einstein）写道：“一个人是整体的一部分，被我们“宇宙”称为“宇宙”，这是有限的时间和空间的一部分。他经历了自己，自己的思想和感情是与其他人分开的事物，这是对他的意识的一种光学幻想。这种妄想对我们来说是一种监狱，将我们限制在我们的个人欲望和对与我们最近的几个人的感情中。我们的任务必须是通过扩大我们的同情心圈子来拥抱所有生物和整个大自然，以使自己摆脱这一监狱。”显然
(Albert Einstein wrote, 'A human being is a part of the whole, called by us "Universe", a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.' Apparently)
