A PLATFORM FOR THOUGHT AND HUMANITY "In generosity and helping others, be like a river. In compassion and grace, be like the sun. In concealing other's faults, be like the night. In anger and fury, be like dead. In modesty and humility, be like the earth. In tolerance, be like the sea. Either appear as you are, or be as you appear" (Mevlana Rumi) "Wisdom is not a product of schooling but of the life-long attempt to acquire it" (Albert Einstein) (Contact Address: firstname.lastname@example.org)
For myself, I found that I was fitted for nothing so well as for the study of Truth; as having a mind nimble and versatile enough to catch the resemblances of things … and at the same time steady enough to fix and distinguish their subtler differences; as being gifted by nature with desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and as being a man that neither affects what is new nor admires what is old, and that hates every kind of imposture.
