It is not possible that we should remember that we existed before our body, for our can bear no trace of such existence, neither can eternity be defined in terms of time or have any relation to time. But notwithstanding, we feel and know that we are eternal.
Baruch SpinozaNature offers nothing that can be called this man's rather than another's; but under nature everything belongs to all.
Baruch SpinozaAfter experience had taught me that all the usual surroundings of social life are vain and futile; seeing that none of the objects of my fears contained in themselves anything either good or bad, except in so far as the mind is affected by them, I finally resolved to inquire whether there might be some real good having power to communicate itself, which would affect the mind singly, to the exclusion of all else: whether, in fact, there might be anything of which the discovery and attainment would enable me to enjoy continuous, supreme, and unending happiness.
